Gary didn't have to tell me they weren't prepared for the wet field, all I had to do was watch the game. On offense, our strategy of getting it to speedsters and making guys miss was never going to work. Our shifty guys would try to make a hard cut and would slip and fall. You can't run those finesse style plays on a wet field. Rain was in the forecast all week, it's unacceptable to not be prepared for it, but we weren't.
My thought on signal gate was that we DID change the signals, but Sonny Dykes became familiar with the system of signal calling, and it only took him a few series to decode the new signals. This will always be a concern as long as Gary insists on calling the defense himself. He wants all eyes on him, he's not going to use a decoy play caller. How easy do you think it is to decode what a single playcaller is doing? Watch the call, watch the play, boom - that's the signal.
Long story short, I think he's telling the truth. Which may be more frightening than anything he could attempt to conceal.
