Alright, here's a vid of an INT "allowed" by Calvin Johnson.
It's the third INT.
At the top of your screen.
The Rams were playing 2-deep, zone under.
Courtland Innegan broke off his zone to go to the side line for the INT.
Look at how CJ seems to never make an effort to come back to break up the play even though he can "clearly" see it.
Look for the vid that says Stafford nightmare first half.
