re: What does iowa do regarding OL coaching that lsu doesn't?

Most of these guys don't end up playing serious snaps until their 3rd, 4th year when they have developed physically. Iowa and those programs like to take on athletes that have the gifts that they then match with the physique.

It would be easy to just say "well why not do that?" but its hard when other aspects of the program aren't ran that way. Thats why you need to retain players like Cole Smith.
