Matt Ryan is a very good QB and he has actually led a bunch of 4th quarter comebacks IIRC
If you want to call it that.
This is typically how at Atlanta Falcons game goes against just about any level of competition:
1st half: Execute flawlessly. Jump out to probably at least a two touchdown lead.
2nd half: Ryan absolutely falls apart and cant complete a pass to save his life. Usually involves some kind of fumble/pick that was pretty bad. Other team starts chipping away, eventually tying it up or even going by a point or two.
Last minute: Ryan completes a pass to Gonzales around the opponents 25-35 yard line and sets up for a game-winning walk-off Bryant FG.
I'm telling you, go back and look at all of their games. Same exact thing happened against Arizona, Oakland, Carolina, and Seattle in the playoffs.
