I haven't gone back and watched the whole game or anything, but as the Minnesota game went on I started picking up Glasgow tipping the snap pretty much every time Gardner was in shotgun. As Gardner goes through his reads and players motion to new positions, Glasgow would be looking back at Gardner through his legs, looking forward for a second or two to get his own reads, look back again, etc.
Gardner would then stand there motionless with his hands ready to get the snap. Glasgow would then jerk his head up, give it a half-count, and then snap the ball. Every time, it seemed. It appeared to me like any defensive lineman could figure out how to time that snap very easily and come flying off the ball. I would like to believe the coaches picked this up if I could spot it from my living room. I'm sure the kid is not even conscious of it, starting his first game at center and all.
I'm not even sure how the shotgun snap is coached (silent? hard count?), but anyone with insight feel free to illuminate us all with your football acumen.
