I'll say it again, it was a great play call - but they got a pick 6 out of it because Schaub made a terrible decision. Is that a straight up gift, maybe not, but they got way more than they deserved out of it.
Now you're just going ad absurdum, which is awesome.
No, he shouldn't give himself up every time there's a possibility of a pick. But when he's up 7, in that spot on the field, that late in the game, with that defense, he shouldn't even think about trying to force something on a play that the defense has blown up.
If he had been in a position to make a good throw to the receiver and they had just jumped the route, different story - but he had to go off one leg while moving in the opposite direction just to get a pass off - no excuse for that in that situation, and if the roles had been reversed and Wilson had done that, you wouldn't be raving about the Houston D right now.
