I guess I am old school (or just plain old.) I don't think there needs to be "A Sack Dance" after he does his job. Is it going to make he a better player? He didn't need to do a dance to get psyched up before he got the sack. Why does he need one after the sack? Will the fans cheer any less if he doesn't do some stupid move?
*Fan in the stands turns to the guy next to him and says, "HEY! I was going to cheer for CM3 busting Cutler's chops but he didn't do any dance afterward so F-em." * PFFFTT.
Be a man. Do your job and got back to the huddle and get ready to do it again.
