I don't recall saying anything like that, but I did repeatedly call it a gimmick offense. My viewpoint is and was that it was a taking advantage of unintentional quirks of the change to the clock rules, etc...
But, he was the best at it! I mean seriously, Gus/Sumlin/Freeze, they all ran a wanna be version of what he ran. This guy was 46-7 in a major conference. In the SEC, Gus has almost 3 times as many losses and less wins, Sumlin over 3 times as many losses and a few more wins, Freeze had over 3 times as many losses and less wins. Also, I should probably point out that Oregon looks like crap now.
All three of those guys at various times were considered at or near the top in terms of SEC coaches, and it's hard to deny that Chip Kelly is the one who really mastered the no huddle hurry up. Now, the downside? The argument is he doesn't like recruiting, he's been away from the game for a while, and teams might be starting to figure out his offense. While true, he doesn't have to be anywhere near 46-7. If he replaces a guy who is 22-12 I think the goal line is clear. He's supposed to give them a chance to win all their games, which I think he offense can do, and he's supposed to be somewhere around the 10 win mark each season. I think those are reasonable goals. This might not be a slam dunk hire, but Chip Kelly has the potential to make his team rather dangerous to play.
The knock on Kelly will be that his teams will be fundamentally flawed, somewhat like Gus' Auburn teams seem to be. Capable of winning games, but not capable of winning them all. But, we're not talking about Urban Meyer or Nick Saban here. Those guys aren't available... the goal should be hiring a guy who can win, and who that might be available has a better track record of doing that?
