Play design was GREAT by Carmichael here. Just have to finish!

Pete has taken a lot of heat, most of which he deserved. The only game the Saints were truly out of it was the game against the Bucs. Had the players executed the plays called in the other games the Saints may be 7-1 at this point. There's a fine line between winning and losing in the NFL.

While PC has had his share of questionable play calls with down and distance, as well as game on the line calls, he doesn't get much credit here when things go right.
I would argue that we should never have to win in spite of your playcaller. I never seen a championship team overcome bad playcalling in meaningful games.
