Offense doesn't always drop off in a bowl game. There were plenty of bowl games around the same time, and offense didn't necessarily drop off in all of them. There have been plenty of high scoring affairs in the MNC, too. It was just an ugly, miscue-filled game for both offenses largely, and I'm not sure that means anything in general. It was just that kind of day. I actually expected a low scoring game too.
True. Offense doesn't have to drop off in a bowl game, but it seems far less likely than an offense will OVER-achieve in the MNC game relative to their regular season than they will UNDER-achieve. I don't know how else to explain the fact that in 2009 and 2010, Oregon was averaging 35-40 points a game and was held to half those numbers in the Rose Bowl against Ohio State and then the MNC against Auburn. Something tells me if those games were played the week after the regular season rather than a month later, it would have been a different story.
I think the pass happy spread does not require a QB who can run at all, unless I am wrong about the scrambling abilities of Kliff Kingsbury, Sonny Cumbie, Graham Harrell, and the like (or New England, 2007). Not sure it has a more downfield presence necessarily than the WCO but you might be right. I thought a key part of those offenses were replacing runs with quick, lateral passes to RB/WRs in the slot that allowed them to make a few yards after the catch. So these short, quick passes. I agree that it does need a good passer though. I'm not sure how much it relies on speed so much as cutting and ability to make plays in space, out of those receivers. Wes Welkers moreso than Randy Mosses, so to speak.
You are right that Texas Tech does not feature scrambling QBs. Note I said it was not a requirement, but is usually a benefit. Cam Newton and Colt McCoy strike me as two QBs who are definitely pass-first, but can run as well. When this happens, the team is deadly. To be technical, I think Texas Tech has more of an Air Raid offense, which as far as I can tell, is basically a pass-heavy spread but without a mobile QB.
Not sure about the pistol, don't know much about it other than how popular it is these days. Really, I think the best offense to combat a defense is an offense that can do anything. Or just enough of variety to keep defenses completely on their heels, because it's not practical that an offense can literally do anything. Again I'll cite New England as a great example of this. Versatility (on both sides of the ball) is what has made that offense dangerous for a long time.
I agree that a versatile offense is the best offense. But if you can't have a versatile offense---
and few teams truly can at the college level---
then the next best thing is to find a few things and do them well. At least then you make the defense have to worry about conforming to YOU.
The worst case scenario is not doing ANYTHING well, which is what we saw at the end of the year this year.
