As a Tennessean, never cared for the Titans. Remember seeing somebody wearing a Titan jersey when they first started at a UT game, and thought that was ridiculous. Sorry, NO good football comes out of Nashville. NONE. PERIOD.
I pulled for Peyton and the Colts...have always liked the Broncos...so yeah..I'm a Bronco fan. Definitely not a Colts fan at this point.
BUT...to be honest, the NFL is just an amusement.
I really can't say that I am a fan of any NFL team at this particular time. I was a fan of Pittsburgh back in the day of Bradshaw, Bliar, Swan, Hamm, Lambert...and could not stand the Cowboys.
As I have gotten older the NFL has lost some of its appeal to me. I do like seeing former Vols do well at the next level, and I do root for anyone playing New England. I guess rather than being a fan of a particular team, I find that I am more a fan of good character. I like seeing players who conduct themselves with class both on and off the field. Certainly Peyton does that very thing. In fact, both Manning's do, and generally I find myself rooting equally for the both of them.
I've been a Bronco fan since the days of Elway. I have renewed interest now. On the other hand i no longer care about the Colts at all.
I agree with the concept that more and more will follow their favorite player wherever he goes than just follow a specific team (exception being those with geographic ties)
