The problem is people not realizing he difference between pros and college athletes. The pros are the top .1% of all college athletes. They are elite and usually have a higher genetic ceiling. They're also older and more physically mature. You don't hit thst point until around 25,sometimes later. It's more about maintenance at that point, they've already built their bodies up, college players are still building. That's why everyone needs to do every lift and not specialize a lot. If someone wants to work on something specific they can do it on their own. Tons of guys in the NFL did a lot of extra working out as well as the programs they were in during college.
