One coach said he's seen defenses throw all kinds of mixed coverages at Jackson, and assorted blitz packages, and Jackson "eats them for breakfast."
"He's an exceptionally quick thinker," the coach said.
This is a huge reason Jackson has been so successful throwing the football. It's not just the accuracy; it's digesting how the defense is attacking him and acting accordingly.
