Tennessee Punter Brett Kern, not Vincent Young is the real reason the titans have won their last 3 games.
Kern was on the Broncos for their first 6 games when they went 6-0. The Broncos cut Kern after their 6th game and have gone on to lose their 3 games since then. Tennessee signed Kern, while sitting on an 0-6 record, after the Broncos made the clearly dumb move of cutting him. Since Kern was signed, the titans have gone 3-0 making Kern, New Orleans, and Indy the only undefeated's in the NFL.
To me, this is a much more logical reason for the titans' recent success than who the starting QB is, especially when the QB isnt playing great.
