I assumed he was hoping to improve his hands this spring, but reports consistently say that he hasn't. Then Flores and Greathouse apparently showed up looking college ready and the writing was on the wall.
I'm not sure why Styles moving on would affect recruiting at all. He got beat out, moved to a loaded CB depth chart, and finally decided he'll have a better chance to play elsewhere. That happens everywhere. Recruits aren't going to look at it and change their mind about ND football because of it.
