Like most have said, he makes some fair enough points... but the pro's still outweigh the con's.
He's a low risk proven winner who has the experience to walk in and immediately get to work without delay, he has a well stocked list of league contacts... he isnt going to be "feeling his way around for a while".
He's also going to bring our atrophied passing game into the modern age, a factor worth its weight in gold.
He knows what a professional QB is supposed to look like, you can bet we're done bringing in brokedick vets and rookies that never amount to shit.
He's going to give a shot at the playoffs year in and year out... and thats the bottom line of why he was such a hotly pursued coach.
