I think on jet sweeps when the box was loaded and the OL was a mess. He had mop up work after an early fumble in a blowout of Purdue and mop up in a bloodletting of IU.
Plus there's the fly sweep factor, which is to say he usually got the ball in favorable spots (also that offense was a weird mess because of some push/pull between OC and HC). So there was some modest coaching malpractice, though with the passing game and a mid-season OL coach change, I'm unsure 200 Gordon carries change all that much.
Yeah, that goes back to coaching then.
If jet sweeps and fly sweeps net so much yardage for the backup, why the hell aren't they doing it with the starter?
I think HCs are married to this idea of starter/backup, and it's antiquated and asinine. And if their play-calling is described as you've said, that HC doesn't know what he's doing.
No, I'm not saying I'd do a better job as HC of a major program, but I would be confident being the nerdy advisor, providing reports each week of how he could improve his offense with simple tweaks.
For instance, if you have a starting RB getting a bulk of the carries with a lower ypc, and his carries are more traditional play-calls, that's an easy fix.
A - you give the backup more carries, period
B - the more traditional carries the backup gets and the more dynamic, diverse carries the starter gets, the harder it will be for the defense to know which is in there to do which
