Because of the QB given those calls from the OC and running the plays.Do we believe offensive coordinators do anything? I mean might as well have kept Applewhite, right? Coffee's improvement and so on, that was going to happen either way, or was it? Remember they also added a guy named Julio Jones, if Applewhite was still there he might have thrown the ball even more...
That aside, let's take a look at the guy named Mark Ingram. He averaged 5.1 yards per rush that season, he got 143 carries. You know how many carries Justice Haynes got, who averaged 5.7 last year? He got 79 carries...
The differences are not solely a result of the offensive coordinator, that's obvious. But when an offense gets better or worse, runs more or less, that's the job of the offensive coordinator! I don't see how people keep looking at the results and divorcing the guy calling the plays from them. McElwain chose to make Coffee the focal point of the offense (and reduce the role of the QB) and it paid off.
If I call a play and the QB makes the wrong reads or sets the OL up wrong or doesn't see a wide open receiver.....or......in a read option, should have handed it off and didn't....or should have kept it and didn't....then we don't have a functional offense no matter what's called.
Then we'll have the games like UGA first half or LSU....everything looks great.
Then we'll have games like OU and Michigan where everything looks like a middle school offense.
