Why don't we just ditch the S&C program since it doesn't seem to matter if players get smaller.
You completely dodged the point. How is a kid who is 6'2" 190 lbs not physically ready to compete for the #2 QB job, but a kid who's 6'1" 195 lbs is?
You're putting a whole lot of weight (no pun intended) into a kid being 5 lbs lighter than when he arrived (if that's even the case) and completely glossing over much more important factors that would determine if he was truly ready.
Does he understand the offense, have good decision making and can he make the throws? Would adding 5 lbs help him in any of those aspects?
