I think they've overestimated how much better players get with coaching. I mean, a lot of these guys have been playing football since they were kids and have been coached since then. If the light hasn't come on by the time they get to the NFL why should it all of a sudden happen now?
I'm not saying it never happens, because there are numerous examples of it working out, but if a guy has 5 years of college football experience and he's still just relying on being hyper athletic (just an example)....
Anyway, let's not let this devolve into Ballard grievances. Go Latu, go Colts!
