It just depends on what is at stake.
I'm going to support the NBA ASG, just because I want to see Rose get the ASG MVP. He might not get it, but I'll definitely check it out. I do the same for the NHL ASG. And if we had someone that could pile on points and win the Pro Bowl MVP, then I would give two shits. Baseball does irk me, like others said, because of the lame home field advantage.
I still like the 3pt shootout, dunk contest, NBA skills challenge, and home run derby a lot. Of course, the home run derby was a lot better when everyone was swapping the cream and the clear.
