Playing with the words. Proper analysis of QBs and INT will show it's only sometimes to usually their fault.
Ah. I see your point. To me, the rule of thumb is that a receiver should catch any ball that hits him in the hands.
A QB should hit any receiver who is open (where, is irrelevant. Just hit him).
A QB under pressure is 50/50. Do you take the sack, lose the down on a throwaway, or try to make a play?
