Look, bottom line, our young backs should have gotten some additional touches last Saturday, especially when Rex started cramping up. Yeah, it worked out when he went back in and scored that long pass play, but sprinkling in a play or two here and there with Green and Heard is to Rex's long-term benefit. Getting 30+ carries a game is an unhealthy lifestyle. Against a team like Northwestern with their run defense issues, we better get some production out of the young guys. The meat of the schedule is two weeks from now. That's when we need Superman for four quarters.
I'm not advocating even keeping Rex out for an entire series. Just rotate here and there for a play or three, keep fresh legs on the field. This isn't rocket science.
And as to the response about one of the backs transferring based on Cody Green's situation--c'mon, be serious. The running back position is fundamentally different from the quarterback position in that you can contribute heavily regardless of whether or not you're a starter. I just read an article in the OWH about the chemistry between the young guys, who apparently all live together. Could a transfer happen? Sure. But these guys are in their FRESHMAN year. They have all the time in the world to make huge contributions to this program. And last I checked, we're not taking another RB in this class. The future is bright for all of them.
