I find it difficult to believe that Belichick will change his MO and use any formation or scheme on any permament basis. He'll adapt, adjust and gameplan according to his opponent week by week. He'll not only base his decisions on his player's strengths but to exploit the given opponent's weaknesses. Such as when he played the Colts last year and used a formation with a 2 man line, droped 8 or 9 players back into coverage had All Pro caliber player like Ty Warren standing on the sidelines in favor of a dime back who barely made the team ,or maybe was picked up the two weeks ago off the street as an emergency roster addition, because he believes that gives his team the best chance of winning.
In the process he'll expect his players overcome any adversity, perhaps sacrifice individual comfort or achievement for the good of the team and most of all make plays like the highly paid professionals they are.
