It really depends on why you root for the team in the first place. If you root for the team and only watch the kings because they are a pro sports team in Sacramento, then there's no point. But if you are a fan of NBA basketball, and root for the team for more reasons than regional location, then there is a point of continuing to support the team.
I agree with this.
I also want to discuss the players.
I've invested a lot of time watching these players as they begin their NBA careers and try to achieve their goals. I watch their successes and their failures, and every day hope that they'll reach their potential.
When they played their final game in ARCO they wore those white throw-back Royal's uniforms. Same players, different name on the jerseys. I was able to cheer for them, root for them, and get incredibly happy when they pulled off the win.
Regardless of which city that they play in, I'm going to support the players.
I root for all of the team's previous players to succeed, provided that they don't play for the Lakers. (Loved you Barnes till you joined the Lakers. Artest, I would have rooted for you to get a ring anywhere else...)
Peja, Bibby, Miller, Kevin, Landry, Hawes, Nocioni, Patrick Ewing, Brockman, House, McGuire, Songila, Price, Brown, ect....I root for all of them to play well, do well, and have success.
So even if you're not a fan of the NBA any longer, you can still watch these games to support the players, and root for them to succeed. I know I will be doing just that, regardless of what happens.
