Grizzlies.... Growing up I was always a Bulls(jordan) fan. When that went down...Penny and Shaq were together so I hitched myself to the Magic. After that crashed and burned. I realized that I was a fan of basketball but didn't really like any of the teams.
Once the Grizzlies came to town I decided it would be a good opportunity to get in on the ground floor with a hometown pro franchise. Last year sucked hard buut...things seem to be looking up for them.
Never really had a favorite team, but I've always been a Shaquille O'Neal fan since his days in Orlando. Just sort of pulled for whatever team he played for until this past season when my girlfriend got into basketball. She too is a Raptors fan and I ended up getting hooked on them as well. Real fun, young team to watch/follow. Hoping they'll have a few nationally televised games this upcoming season as compared to the 0 nationally televised games they had last regular season.
Portland Trail Blazers. I can walk to the Rose Garden in about 10 minutes from my house... Followed the Mavs during the Jail Blazers years. I just couldn't manage to root for a front office that inept, and a team with that much poor character.
