We don't have enough star power to be serious contenders. We have a bunch of role players that are playing really well right now. That's all good and everything but role players don't win championships.
How much star power does a team need? If Pierce can gain some momentum, Bradley takes another step, and KG just does his thing we would have plenty of star power. Thats hoping for a lot but the odds of losing Rondo and Sully in the same week were pretty slim, why not hope for the same odds in the other direction. Be a fan of this team. Enjoy what they give you. It might not be a banner, but it could still be fun.
How much star power do you need? The NBA is based soley on star power. Teams that win championships have players that can take over games consistently. At one point, this was KG and Pierce. They can still do so at times, just not on a regular basis.
When a team has 2-3 all stars/superstars not named Kobe (brick) Bryant the team will most likely contend. Look what the addition of CP3 has done for the Clips. Heat went from nothing to finals appearances and a championship. And look no further than our own 24-55 2007 celtics team to understand what star power can do for a team.
Basketball is a team sport and role players are very important. However, you need stars to contend. That being said, I do agree with your last line. Contention or not, I'm enjoying this fast break team.
