Atlanta Braves Baseball all summer long!
Tennessee Titans Football
Tiger Woods winning one more tournament!
Serena Williams winning one more Major!
* only explanation needed is I was born & raised in Memphis, moved to GA at the age of 22, was a Cowboys fan before the Titans/Oilers left Houston, and started watching Vols football in 95' at the age of 7.
I used to be a Jets fan in the 60's. Haven't watched nor gave a darn about the NFL since Peyton retired.
Used to be a big Yankees fan. My baseball fandom retired with Hammer'n Hank.
Supporting/rooting for any other college team is, in my little world, akin to treason.
These are the only teams I care enough about to keep up with. But baseball (and the Braves) were my first love. My whole family are big VOL fans. Dad, sister, and brother are all UT alumni. I was the black sheep that went to MTSU to "get away." But I didn't start following football more than casually until I was about 10-11 when Peyton became a household name. A coulpe years later, we won the natty.
As far as the NFL, my family never had strong affliations to any team when I was growing up. We watched the Braves every Sunday afternoon on TBS, not the NFL. The Super Bowl was pretty much the only NFL football I watched growing up and my "favorite team" changed based on who was playing in the Super Bowl. I was a Cowboys fan for a few years, then I was a Broncos fan. When the Oilers relocated to Nashville, we started watching a little bit, but not significantly. Then I recall listening to the Music City Miracle on the radio while me and dad were cutting down trees and stacking fire wood. I felt the excitement from Mike Keith calling that play. I've been hooked ever since.
EDIT: I added MTSU to the list as well, because I do root for them to do well, I just don't follow them at all.
85 Tennessee Mainly football
5 Dallas cowboys
5 Atlanta Braves
5 Duke Basketball.
If i had to pick one it would be 100% Tennessee football. All year round i talk about it to family friends and coworkers. The others are just fillers until fall gets here.
