Indiana won't be the last fast no-huddle offense Michigan's defense has to contend with this year.
Ohio State's uptempo no-huddle scheme, called "jet" has a high-speed gear that Urban Meyer calls "inferno." (SI.com link to Pete Thamel story on his time inside the OSU - headset conversations.)
Having seen OSU for myself in Columbus, they really can turn up the speed and keep it there for an entire drive; "Jet to Inferno" is right. IU can do some of it, but isn't as crisp as OSU or as fearsome rushing as are the Buckeyes. Still, IU took advantage especially on some second downs with super-quick snaps. There were at least a half-dozen plays where Michigan's defenders were not set, and a number of them went for big gains. I can think of one play where Channing Stribling was looking in at our linebackers for signals when the ball was snapped. He then reacted after his man in coverage broke off the line, then he looked back up just in time to see the IU QB pump fake, which he completley bought, and was then beaten. The whole mess really started pre-snap.
Michigan tried something new against IU; to get clearer signals in from Mattison, they first put him in a bright maize jacket, and then they had two graduate assistants standing behind Mattison hold up towels so that defenders would more quickly pick up where to look for Mattison on the sideline to get the signal.
It almost looked as if they were "hiding" Mattison from somebody behind the Michigan bench stealing signs. But I'm certain that they were highlighting Mattison's position along the sideline for the benefit of guys on the field. It was altogether a bit of a panicky affair, on the Michigan sideline.
It all calls into question the extent to which Mattison is substituting players on every defensive down, and the extent to which Michigan's DL is switching positions after the offense sets up. It was nothing less than a huge problem against IU; and it may be exploited a lot more as the season goes on. Does Mattison's defensive scheme need a lot of adjustment for good NCAA no-huddle offenses?
