I think that this Iowa situation is going to affect a lot of football programs and how they're individually run in a positive way. Coaches are going to use that as a good example of what not to do and how they can help encourage the conversations within the team.
The teams with older coaches may very well be the ones with the most issues also. I'm in my later 40s and know I'm kinda at a dividing point where racism wasn't just a given that you would be that way and things had started to change during my growing up. Those younger have had a more naturally diverse background generally, whereas those older than me had lived through a time where segregation was not seen as unnatural.
