Dude has a great resume. Protege of his dad, mentored by Pete Carroll at USC as OC with one of the most prolific offenses of all time.
He only had 1 year w/ Raiders (Davis - enough said)
1-year at UT - recruited the shite out of that place given the crap circumstances and didn't exactly bomb.
You say the guy has a great resume, but immediately make excuses for two of the three head coaching jobs he's had. And he's not setting the world on fire at his current one.
This (USC) is his first real job to properly evaluate him apart from his resume/background.
His two years at Oakland and Tennessee are part of his resume and background, but it can't be used to evaluate him?
