Well, yeah, that too.
But I think the fact that 2/3rds of the plays that came out of Gannon's head were plays the Bucs knew front & back didn't help, either.
I remember Gruden laughing about it later, saying something like "I told them 'this is what we called them when I was there, they've probably changed the names and changed the plays up slightly, but this should be close enough that we can adapt once we see it."
And then it turns out they changed NOTHING, and the plays were run exactly the same, with the exact same names.
Fuckin Callahan.
Holy shit.
I wish the Raiders were competitive still, they're the best bad team in any sport.
