Mac got two TD's that should have won the game. He made two more throws that would have put them in FG range which would have won the game.
He did enough to win that game. Even if you ignore all that, and just watch the game.... at worst he made the big pass that set up the go ahead TD and the defense **** the bed and he got screwed.
If you can go through 4 individual game changing plays the QB got hosed on by his coaches or teammates and all 4 would have won the game... and the QB should have had the game won without them... you can't blame the QB. Carr deserved to win less.
