Thats pretty cool. If he is a leader, the other fellas will follow. If they dont, it's because they wont consider him their leader.
My reasoning is that, Bowman has not been on the field a lot with the rest of the group the past few years, right? You know, not battle tested over time. Throw in some of the guys that have a lot of pride in themselves (for whatever reason, i.e., "but I'm the pre-season all big 12 selection - I'm the leader"... whatever) and they leave him out by himself.
Just my opinion if they dont follow his lead, that's why I think that. Pride. And nothing else. And I would be disappointed if they didnt. It's pretty clear what he is saying.
What Bowman did is brilliant. They all need to do the same. They all need to be one & on the same page.
Peace-OUT!
