I haven't read anything to suggest Coach Jackson would or would not be returning. But being that he is a Lloyd (the only Lloyd) holdover on the RR staff, I would imagine he is a favorite to return. His recruiting contacts in Texas and Lousiana have always been a plus.
Should Coach Jackson not return, one interesting name to consider would be Tyrone Wheatley who is doing a great job as RB coach at Syracuse. Not sure whether he has developed strong recruiting relationships just yet in his young coaching career. Again, my money is on Jackson coming back.
Fred Jackson's assessment of Brady Hoke? "He's got the speed of Desmond, the size of Branch, and the leadership of Griese (without the Scorekeepers part)." Not bad.
