IMO story of the game is KC's health. If the Chiefs come into the game fully healthy and ready to play, it'll be a great game. I wouldn't be surprised at all to see a low scoring outcome, 17-14, 24-21 type of game.
Both teams can get after the QB. Both teams have an offensive capability that makes them really difficult to stop (run for Philly, pass for KC).
KC's offense is more dynamic, but the OTs can be a problem. Philly's pass rush off the edge is legit.
Philly's run game, including the triple RPO, is excellent. KC's DL is stout, esp Chris Jones, who was the best DT in the league this year & truly disruptive (better double & triple team him every snap, else he will blow up your offense).
This should be an outstanding Super Bowl
