I don't think Early had quite the same personality dysfunctionality as Bragg, but yeah - someone with his disposition would not have been a good commander.
I must side with 5fish here - though I would be reluctant to give Early army command.
He'd be jumping from division to corps to army - bit much, if you ask me.
Would have been a tough opponent for Sherman, but of course the question on sending him is "How? When?"
That is a problem. And one I'd like to see answered before figuring out if it would have mattered there.
Note: My memory on when Early was sent to the Valley is deciding to go AWOL. I know I've read it, I just can't recall.
But the "how" is a biggie - the railroads are shot.
