It was too a great throw. He put it in a good spot when there wasn't much of a window and the defender had great coverage.
if the coverage was that great then he shouldn't have thrown it. and if you want to define a great pass as any pass thrown that can't be intercepted and requires an incredible play by the receiver then you are dumbing-down the word 'great'.
hate the cliche - great play by the QB: he threw it in the only place the defender couldn't get it. well then maybe he shouldn't have made the throw 
Maybe he shouldn't have made the throw, but CCQ zipped a pass 30 yards through zone coverage and hit Thompson in the hands.
