Boulder — College football coaches are the type who protect their play calls as if they were nuclear codes.
The pervading paranoia about having play calls stolen has created creative methods of signaling, from coaches or players using giant cards with seemingly random pictures on the sideline to backup quarterbacks waving their arms like inflatable mascots you see at a used car dealership. It all leaves defenses left to gauge what’s real and what’s subterfuge.
So Colorado coach Mike MacIntyre isn’t about to let the world know exactly how the Buffaloes are using signals to ramp up the tempo of their offense, but he did offer a glimpse ahead of the team’s home opener Saturday against Idaho State.
