He was unblocked on his two sacks........ But like someone mentioned, he was "blocked" on his sack that got taken away via penalty.
AND he had a near sack with :12 seconds left that would have sealed it but Bree's arm was going forward (also blocked).
Don't try an discredit the game Spencer had. Him and Ware bodied up that those Saints tackles.
First it was "Yeah he's doing everything good, but he doesn't have the sacks to show for it."
Now when he gets the sacks, "But he was unblocked."
*waits for* "Yeah he's getting sacks, but that's only because Ware gets so much attention."
