Byron Maxwell and Super Bowl "Guarantees"

Byron Maxwell, cornerback for the Philadelphia Eagles, recently guaranteed a Super Bowl berth. Here is my only reaction to his guarantee, and any other guarantee made by any player in history. So what? What are they supposed to do, think their team isn't going to make the playoffs? Super Bowl guarantee's among other things should actually be viewed as a positive statement. I inferred one thing from Maxwell saying this. What I inferred was that Maxwell really believes in Chip Kelly's team, and he thinks they can be very good. A very underrated attribute to good teams, is the coach getting the players to buy into the system. When every single player buys into what the coach is doing, they play their hearts out and leave everything on the field. This is the root of the common saying that a coach gets the most out of his players. A terrific example of this is the Seahawks over recent years. Believe it or not, a lot of their current star players weren't born star players. Michael Bennet and Cliff Avril were both castoffs from teams and they have become vital pieces in both the Seahawks Super Bowl appearances. It's important to get your players to buy into the system, and I think this shows that at the very least Byron Maxwell has bought into what Chip Kelly is doing, and I'm sure other Eagles players have too.
