My brother was an OL at University of Houston. He topped out at a lean 290. Just couldn't gain more. 8500 calories a day. Waking up in the middle of the night twice to eat. Ultimately, he had a metabolic problem which medically retired him early.
I agree with you and many other sentiments. Others indicate that putting on pounds is all want and discipline (it can be): (1) but is it healthy? and (2) does it make the athlete better in terms of speed, mobility, agility, etc...? Every individual's body is different (genetics, growth plates, etc...) and IMO natural bulk and growth is where players excel and a team should want--
a healthy strong build. The added nutritional programs available help and in theory (absent a metobolic problem) should get each player to their natural build maximizing the best: strength, speed, agility and football product. It does require effort, however the body has to cooperate as well.
A certain % of players like your brother build some on campus but max out and cannot meet the position's requirement. Then it guess it is back to good ole' the HGH, roids days... or finish out your football playing days, graduate, and onto a new and exciting profession. If he succeed in building his body the wrong way, he may have played more but be cripplied the playing days are over.
I think Yuri Wright's issues were not just his skinny build/frame but his height as well. CU was banking on his body frame growing--
YW and we lost. All of us are born with our natural (genetic) growth plates, so you can't really change that much. If his body growth plates do not broaded shoulders, it is tough to gain tons of upper body mass. I repeat, Mike Mac (not the coach who recruited YW) came completely to YW's defense speaking about his retirement and was candid about his growth limitations--he did not say YW lacked desire or discipline, as he kept him on schollie to graduate. He was sorry body limitiations did not work out better. Also, YW had 2 known concussions when playing for CU, not sure if he had any previous. As a coach, I would have a tough time putting a 165 pound player in a D1 game as a DB with concussion history. I disagree with @Toverson, that YW was 6'1", I never thought he was that tall. However, if YW had grown to like 6'3" I'm sure he would have made 190 - 195, and he could have been like Spoon--maybe not to the pros, but a solid college player.
On the other side of the coin, there are some players who bulk up well past their natural healthy body. Mandwich and Boz did this unnaturally. I love LaViska Shenult, one of my top 5 Buffs, and he really bulked up (a weight room monster), however some of his bulk looked unnatural to my eyes--almost over built. Still love the guy and root for him each game, but his NFL experience has been a mixed bag given injuries. It is always 6 of one 1/2 dozen of the other. 49's McCaffery lost some weight adjusted his game and had another breakout season.
MLB's pitching injury woes have been highlighted this season? To what lengths can an arm can go without injury? What % of the entire population out there can throw regularly in the high 80 - mid 90, or high with a wicked slider, cut or sinker and not be subject to arm injuries? In baseball, they bulk these guys up with moster tights and huge asses for more power, yet the arm injuries crow up everyweek. Football has it differently, in the NFL how many guys (grown men) under 185 can excel at positions requiring regularly hitting, tackling, blocking, etc...?? In college football, we are doing about the same as the NFL, except we are dealing with growing young adults/athletes, not grown men.
