I'm sorry, but this post is rife with uninformed speculation. I'm not saying Chris Doyle is the greatest strength coach of all time, but there is no such thing as a strength program that can turn mediocre talents into great football players. I know that people loved to view guys like Bob Sanders as products of a great workout program but if it were that simple, Iowa would have a limitless supply of Bob Sanders' every single year. They haven't had one since. It doesn't matter how good the workout is, how much stronger, faster, bigger, a guy gets if it still isn't good enough based on their ability.
I've noticed that some fans like to pretend that good linemen just need to be big and strong. Being big and strong are the two easiest things one can accomplish with the right frame, diet, and workout routine. Having good footwork, understanding leverage, etc., is much harder and isn't always teachable. Talent plays a big role.
Surely I'm not the only person around here who played football with some weight room warriors who still failed on the football field. Conversely, I'm sure I'm not the only person who witnessed guys who were pathetic in the gym but could utterly ruin people on the football field.
The weight room can make somebody a lot better, but it can't produce a good football player when there's not enough to work with from the get-go.
