From an article in 2016 after Kelly’s uptempo offense met it’s demise in 2015. Quoting a couple of guys that have “watched football closely” and, btw, won a few games.
“At least for a season, the story was much the same in the NFL, and Kelly’s methods quickly garnered the NFL’s attention. “
They go really fast and try to wear the defense down or force [a] communication issue on defense so … even if you’re aligned right, if you’re not able to get your assignments done quickly [and if] there’s space in there, somebody gets free,” New England Patriots coach Bill Belichick
said of Kelly’s offense in December. “The speed that they go at, it’s hard to get much communication in. It forces you to kind of simplify things defensively.”
And it worked for Kelly with Philadelphia until:
“But another element is that while the no-huddle works in the NFL — and Kelly’s 2013 opponents were largely unprepared for Kelly’s pace — it’s not as effective as it is in college football for a very simple reason:
The NFL doesn’t permit teams to ever reach the warp speeds Kelly’s Oregon teams typically operated at. While NFL coaches aren’t permitted to openly critique officials or league policy, it’s well understood in coaching circles.
“In the NFL, what they did is the officials stand over the ball until the officials are ready to call the game,” Alabama head coach (and Kelly friend) Nick Saban
explained in 2014. “The coach at Philadelphia ran 83 plays a game at Oregon, and runs 65 a game in Philadelphia. …
When they went to Philadelphia in the NFL and they were going so fast, the officials said, ‘We control the pace of the game.’ The league said, ‘The officials control the pace of the game, not a coach.’”
Hmmm I guess the original poster was right. They aren’t allowed to go fast in the NFL.
And funny, Nick Saban thought at the time that “coaches dictated pace”. But then again, what does he know?
