Look I didn't like Reggie while at USC cause of USC and the hype. I said he would have a hard time once he get's to the NFL and he is by most people's thoughts. However he is really not having a troubling time at all cause he is doing what the coaches are asking him to do. This kid is incredible...he could take the T.O. route and as far as I know he has not even thought about it. This kid is having one hell of a year for this team cause he is being a team player. Something to many people on this board forget about.
Now as far as your question, yes he would have had the same type of career or heck it might have been better. The player's in the SEC are close to the caliber of player's Reggie is and that would have made him even better. Think of him running the ball at Auburn the year they went undefeated with Brown and Williames, think of him running the ball at LSU the year they won it all and you should have your answe.
I think Reggie would have been just as dominant in the SEC and i'm a big SEC fan. It's just a very different game in the NFL. Defenses just aren'tgonna let him squirt around the corner for a huge gain.
