It's honestly this, when it comes to Kenny at least. Anytime someone calls his show to argue with him over Kenny he ramps up the hyperbole to bait the rubes who call that think it's a valuable use of their time. The "Kenny, Kenny, Kenny!" act is just that, an act, and it works.
It's just hilarious at this point to watch the replays of other games and see even the worst teams led by inexperienced qb's connecting on 50 yd bombs for td's week in and week out, and simultaneously wonder how it's possible for the Steelers to make it look so hard to do as often as they do.
