STANFORD, Calif. -- David Shaw swears he understands. Shaw, the Cardinal head coach, knows theres a limit to how many times junior Christian McCaffrey can take the ball and be effective. The latest test comes Friday night, when the No. 7 Cardinal play at No. 10 Washington (9 p.m. ET, ESPN).He cant take every single rep and be able to survive a 13-, 14-game season, Shaw said. He cant. Even at that age, in the best shape of [his] life, and a phenomenal athlete, probably one of the best-conditioned athletes in the nation. Somebody else has to take some reps.Over the course of McCaffreys record-breaking 2015 season, the running back carried, caught or returned the football 424 times. Thats 30.3 times per game, way more than any other FBS player in the nation. It worked out pretty well for him. He broke the single-season all-purpose yards record (3,250) set by Barry Sanders in 1988. McCaffrey finished with 3,864 yards.When Shaw and offensive coordinator Mike Bloomgren stand on the sideline and look down at their call sheets, they seem to become every 10-year-old who ever ripped open a one-pound bag of M&Ms. How do you stop?It takes a concerted effort among the coaches, Bloomgren said. If we say, Who is the best for this [play]? It usually comes up being 5 (McCaffreys number). You have to be really careful. If we put 25 pounds on him, Id probably play him at guard. At the same time, we say it every time we watch a game. Hey, he played X number of plays. And its too many.Three games into his junior year, McCaffreys workload has ticked upward -- 32 times per game. He has 79 carries, 12 receptions, three kick returns and two punt returns for a total of 635 yards (211.7-yard average). The 91 carries and catches are 59.9 percent of Stanfords total this season. Thats 13 percentage points higher than the second-biggest ball hog in the FBS, Donnel Pumphrey of San Diego State.OK, its not fair to call McCaffrey a ball hog. He isnt calling plays. And in Shaws defense, sophomore running back Bryce Love missed the opener against Kansas State, and quarterback Ryan Burns played little before winning the starting job in August.We live in an age of specialization, with personnel groups shuttling on and off the field every down. Yet McCaffrey is as evergreen as the tree in the Stanford logo. How much is too much? What is the limit?The Stanford coaches dont think in numbers. Shaw mentioned 25 carries, give or take. He checks the halftime stats to see if McCaffrey has too many touches, or too few.The other thing thats hard? Bloomgren said. The kid doesnt want to be out of the game a single play. If he were asking, Can I get a break? that would make it so much easier for all of us. But hes the last one that wants to take a play off.McCaffrey dismisses the pitch count, too, although he said the USC game, when he had 31 carries, three catches and a kick return, has been the toughest to recover from.Sometimes youll have 30, 40 touches in the game, and youll feel better than if you had 22, he said. It depends on where you get hit and how you get hit.McCaffrey expected his workload to increase this season. He is playing more as a slot receiver, hoping to get one-on-one with some poor linebacker unable to match his rare combination of speed and strength. Shaw stressed the difference in McCaffrey between last season and this, the physical maturation of a 19-year-old who turned 20. But theres also a big difference in his preparation.McCaffrey assesses the condition of his body with the care of an NFL veteran, spending a total of three to four hours before and after practice to prepare for and recover from the workload. Foam rollers, stretches, Pilates, one minute in the hot pool, two in the cold, and back again for 30 minutes.Last year, I was doing stuff where I didnt know if that was necessarily the best thing for me to do, McCaffrey said. This year, OK, Im having a little bit of tightness in my adductor. I know I need to get my glutes back firing. I know my body a lot better. I can pinpoint and find exactly what I need to do.The result is a fresher back. He feels better on Monday than he did last season. He accepts that he isnt going to do much physical work on Monday. He understands that Love needs the reps.Last year, we would sit him out of practice on Mondays and he would pout, Bloomgren said. Body language. Now he understands its part of the process.As Burns matures, Shaw and Bloomgren hope the quarterback will be able to take more of the responsibility for the offense. Love has proven in the past two games that he is an effective counterpunch to McCaffrey. Until that really happens, however, Shaw said, the offensive burden is going to be on the offensive line and McCaffrey.Going into a game, I know that Im going to run a lot, McCaffrey said. I know Im going to have a lot of volume, and I know that Im going to get hit a lot, which is great. Sometimes we try to deliver some blows, too, try to break as many tackles as possible. We know its going to hurt the next day. Thats why we love the game. Khalil Mack Authentic Bears Jersey . You can watch the game live on TSN at 7:30pm et/4:30pm pt.

EAST RUTHERFORD, N.J. -- Other than the elastic brace on his right knee, there was no visible sign that age was catching up to Eli Manning as he entered his 13th season as the New York Giants quarterback.The 35-year-old hasnt changed much since taking over as the Giants starter halfway through his rookie season in 2004. Hes healthy, even after starting the last 183 regular-season games. He can make all the throws and seems to be enjoying himself working within Ben McAdoos West Coast offense.Even handling the media is a breeze: When asked two questions at the same time Monday following training camp, Manning wasnt thrown off in the least. He answered the first, then quickly answered the second without having to be reminded of the question.I used to just kind of roll out of bed and go practice, Manning said. Now I need about an hour to get loosened up. Its just maintenance. Ive gotten in the routine of doing it over the years. I see the difference and have stayed with it.The Giants rely on the two-time Super Bowl MVP. Without him, Odell Beckham would be wasting his time getting off the line of scrimmage. Its a role Manning accepts.I think as a quarterback you have a big responsibility, Manning said. You have to play well, take over and I have to do my job and play at a high level. I understand that, I demand that of myself anyway, so I dont think you try and put any added pressure.Manning, who has not thrown an interception since the opening 11-on-11 play of training camp, is going to be patient with his passing game early on this season.Other than Beckham and Victor Cruz, there are a lot of new people. Second-round draft pick Sterling Shepard shows promise, and Dwayne Harris and Geremy Davis are expected to do more entering their second season.However, they have a lot to learn, as do the seven other free-agent receivers in camp.I thinkk you just understand that mistakes are going to happen.dddddddddddd ... I try and kind of tell them things that it was tough for me to understand the first time, Manning said. That means talking the receivers through their mistakes, hoping they do better the next time.Theres one veteran who may benefit from Mannings help, too. Cruz has been limited to six games over the past two seasons by knee and thigh problems. Though Manning feels Cruz has looked sharp, he knows catching balls in game situations is different than in practice or catching from one thrown by a machine.Now hey, you have to turn back, youre running full speed, you have to adjust, hold a defender off a little bit, just making those tough catches and adjusting to the ball in the air are things that hes doing much better now Manning said. He just had to get some live action and is playing some football.Manning will get a chance to see how far the offense has come when the Giants host to the Miami Dolphins on Friday night.McAdoo has not said how long Manning will play Friday. He wont even say whether he or offensive coordinator Mike Sullivan will call the plays; McAdoo did it for the past two seasons as the offensive coordinator before taking over the head coaching job from Tom Coughlin.Game notes McAdoo said third-round draft Darian Thompson is the favorite to start next to Landon Collins at safety. ... McAdoo on Mannings reaction after being intercepted on the first play of training camp: Mike Sullivan has known him for a long time. He says it all the time, `If Eli wasnt playing football, hed probably be the worlds greatest poker player, and he didnt flinch. He just keeps playing.---AP NFL website: www.pro32.ap.org and www.twitter.com/AP-NFL ' ' '
