Assuming Carlos Hyde returns for his Senior year.
Depth Chart 2013 with Rod Smith = Carlos Hyde - Senior, Jordon Hall - RS Senior, Rod Smith - Senior, Bri'onte Dunn - Soph, Warren Bell - RS Freshman, then any Freshmen.
Depth Chart 2013 without Rod Smith = Carlos Hyde - Senior, Jordon Hall - RS Senior, Bri'onte Dunn - Soph, Warren Ball - RS Freshman, then any Freshmen.
Depth Chart 2014 with Rod Smith = Rod Smith - RS Senior, Bri'onte Dunn - Junior, Warren Ball - RS Soph, then any Sophomores and Freshmen.
If Hyde does decide to leave, if I'm Rod Smith I'd want to play in 2013 and compete with Jordon Hall.
This would be a move like Sabino did after his Junior year. Then this year in his RS Senior year he had a very prominate role.
Smith has shown flashes of brillance, but with Hyde and Hall coming back Smith's touches would be limited in his Senior Year. After a Red Shirt, Smith could be the MAN. With 4 years of experience and 2 years in Meyer's offence.
Considerations: Jordon Hall could be used as Slot instead of RB. It could be considered a self centered move, but definately the best for Smith personally. Sabino did this whenTressel was coach, how would Urban feel about the request? Miss playiing on a National Title contender in 2013, or is a National Title more likely in 2014 when Braxton is a Senior?
