He has definitely turned a corner. For the longest he was a manager type whose best asset was not having brain farts. Tonight he was as elusive and extended plays as well as Kaepernik and Roethlisberger, and that's saying a lot. I'd say his propensity for not making mistakes is still his strong suit, but his mobility and sticking with the play to the bitter end has really made strides. Kaepernik probably actually outplayed him overall, but Flacco gets the hardware.
In the end, I was actually hoping that the 49ers would take the lead to see how Flacco responded. They showed him sitting on the sidelines as the 49ers were knocking at the door and he looked so serene, reminded me of Joe Cool Montana. Was really wanting to see if his calmness translated to crunch time performance.
