“Usually,” Bradford said from his home in Oklahoma City, “when you get to go to a new team, you’re going somewhere that’s rebuilding, or somewhere starting over. How often do you get to a team that’s won 10 games the last two years?

“From afar, it looks like a blast to play in the offense. I love the tempo, the mindset. They’re trying to score points every time they snap the ball. Very quarterback-friendly. The ball’s getting out quick, always places to go with the ball. If you’re getting heated up, there’s a place to go with it, always. Constantly putting pressure on the defense. I wish I had more knowledge of the offense to go into depth there. They’ve been top five in offense in both of his years there, and you don’t do that without creating a lot of explosive plays. It almost seems like they go short, short, short, almost lull you to sleep and then they’ll blow one by you. I feel it’s similar to what I did at Oklahoma—playing fast, putting pressure on the D.”

Note the accented text. Nick and Vick both had a tendency to frequently hold the ball and take sacks. These are two commandments that Kelly preached when he first came to town: get rid of the ball fast and don't take sacks. These are two things that, from what I've read, are part of Sam's game.
