Brian Costello of the NYT:
"Marvin Lewis called Rex Ryan before the game to hash over some details, one of which was to request that he not run the Wildcat against him. Ryan obliged his former defensive coordinator from their time in Baltimore,"
Marvin lewis takes it seriously. For sure.

Ed Kilgore: "As for the preseason, coaches and players will tell you the games mean something because, well, they DO keep score after all. But that just isn't all that true. We all know that Marv Levy could have cared less about the pre season during the Bills Super Bowl runs, but once the regular season kicked off, his teams were ready to play."

That's three well respected coaches and numbers telling you that they don't take starters playingin preseason game seriously. Coaches’ primary goals are to have a virtually injury-free, established 53-man roster, discover a few guys, and gain experience and reps.
Essentially, for coaches, preseason is the main opportunity to focus on the players by developing talent and teaching the game.
