...They didn't have to burn half-a-minute waiting to see if the Pats would blink and call a time-out prior.
They also didn't have to throw it INTO all those bodies that were there to allegedly stop the run.....
It's called a fade where the throw is only catch-able by YOUR receiver.
They didn't have but a half minute. The Pats had the lead, why would they want to call time out? The fade certainly could have been called, but it's a higher risk of incompletion than the inside slant off of a rub off play.
