Character concerns will drop almost anyone. Where it drops you to is an unknown. Your performance on the field. Is a huge factor tough. Along with what the character issues were.
For all we know. Thomas may have been told to move along. That doesn't change the fact. That many of these guys are making bad choices.
I know what you're saying - I just have a different and unpopular outlook on it.
Shaq, Pinckney, KJ, Hill - these were all "ball out your Senior year & improve your draft stock" candidates this year, and I don't think any showed much improvement as a player or in their draft stock from where they were as a Junior. Same with Jaquan & Mike Jack last year.
I think in reality, all these "guys who made bad decisions by going early" wouldn't be drafted any differently by coming back for their Senior year.
