Would guess that RB is one of, if not the, most easy plug-and-play positions on the field. Hit the x hole, bounce outside, etc and run like heck. Ergo, there are many prospective players out there that can do that. Might also opine that the coaches are looking at leg size, drive, and trying to ascertain how big the 'heart' is. If one looks back at tOSU's Heisman winners, one might notice that the majority (all but Troy Smith) are RBs. Also goes back to the OL....if the holes are not there, kinda hard to run through them.....either way, tOSU will fill it's numbers at the position. After all, there's always the portal...
