This is nothing to really brag about, but I would bet I've seen Paul Johnson's triple option offense more than anyone since I was living near Annapolis and went to a lot of Navy games. Trust me, that guy can coach circles around almost any other college coach.
This year, they'll still be in learning mode, but once his GT team masters the calls and reads, this offense will be successful. The thing with Paul Johnson is that, to the casual fan, it looks like they are running the same plays over and over. In reality, Johnson is constantly changing blocking schemes as he sees the adjustments the Defense is making. I swear, the guy is uncanny in his ability to constantly change schemes and stay one step ahead of the other team/coaches. Trust me, many a team has tried to "stack the box" and "shadow the QB" and every other conventional wrinkle. Heck, Greg Schiano was D-Coordinator at Miami during some of their glory years and the first year he faced Navy he tried that and Navy put up 55 points on him. After that, he used all summer and changed the schedule to add an open date just to prepare for the next meeting (which Rutgers won handily after Navy's QB broke his leg in the first quarter).
I saw that offense move up and down the field against some very good teams (and no, I don't include Notre Dame last year). Over the last 4 years, I saw them run the offense and pile up yards against a good Wake Forest team, a good Rutgers team, Boston College in a bowl, Maryland and others. And those who doubt can't really think he won't have better players at GT.
The thing I saw with Navy against the really good teams was not that Johnson's offense could be stopped. Rather, the service academies weaknesses are on defense because they don't have the speed or size to match-up. That forced Navy's offense to be near perfect and have to score almost every time they had the ball. It was like tennis, if they ever lost serve (turnover, not making a 4th down conversion), they would have trouble against these better teams.
So, I think getting GT early this year is an advantage. But when they come to MSU in '09, our players and coaches better be on their A-game, because Johnson will have many more wrinkles to throw at us. Plus, this is a guy who was the Offensive Coordinator at Hawai'i years ago and they aired it out pretty good, so don't look for him to run the EXACT offense at GT he ran at Navy where speed is not really an option. The guy is a winner and I expect him to continue to win like he has everywhere else.
If you want to read something on his offense, here's a good explanation - grab a chair, its long:
