I have never been a big fan of bringing him back, but it does seem as though it's a no lose situation for the Fins. If he is not a bigger distraction than help, it could be interesting.
Brown will not be holding up very well in Dec, if he starts getting 30 carries a game. (He always shared time in college and never had to deal with being the only featured back) It is not that he can't do it, just that he never had to. It might be nice to have a solid backup. By then Ricky will be over his suspension and could have worked his way, slowly, back into playing shape. This would be about the EXACT time we need to spell Brown.
If we start out 3-1, which is not likely, but possible since we play so good at home early in the year, I think most players will not want to risk adding him to the mix. However if we start out 1-3 and Brown is having rookie gitters getting started, then maybe a few more players would accept his return.
I think due to Ricky being such a loner in the locker room and not being a real rah rah guy, if players do let him back on the team he will not be much of a problem. But if we started out good and it then went to crap after Ricky's return, bar the door b/c he would be abused as the scapgoat. IMO
