Some thoughts:
This game comes down to two things, defense and experience. The Patriots have the edge in both. They were just here 2 years ago, and have a defense that can limit Ryan and the Falcons offense. The 7 times the top scoring offense has played the top scoring defense in the Super Bowl, the defense won 6 of those times. A top scoring offense hasn't won a Super Bowl since the 49ers years ago, but they also had a top 3 defense. Just ask the 2007 Patriots, 2013 Broncos, and 2015 Panthers about how the top scoring offense fares in the Super Bowl. The Falcons also have 4 rookies starting on defense, including two in their secondary at free safety and CB. Brady will target them early and often as he did against the Steelers 2 rookies Burns and Davis. Quinn tends to play a lot of zone coverage which Brady also eats up. And while Quinn has been here before, the majority of the team have never played in a game on this level, and I think that will come into play as well. The Patriots are 8-0 on the road this year, and the Falcons defense is 27th in pts allowed, 25th in yards, and 27th in passing yards. I expect a good game, but its hard to not give the edge to the team that's been here multiple times in the past.
