I would be much more worried about filling the program with the 'wrong' type of kids if RR didn't have a history of dropping players at the first sign of trouble. Everyone knows the examples, but it's obvious that RR has zero tolerance for mistakes while in his program. I doubt he would risk Dorsey if he didn't believe fully that the player has turned a corner and is willing to push himself.
We all did dumb shit as kids. Dorsey's situation was different than mine (i grew up a white kid in suburbia) but had I been caught doing some of the dumb stuff I did my record wouldn't be much different than his. I grew up. I assume he will also.
This is a far cry different than Watson and MSU's history. Watson wasn't 16 when he put a kid in the hospital and ended a hockey players future. Watson was a convicted felon with a violent crime. Watson was welcomed back with open arms and did it again.
Had OSU landed this kid, I doubt his past would have even been reveled unless he screws up in college.
