The thing that bothers me about the NBA is that so many teams just have no chance before the season starts, much more so then any other major sport in North America. The Raptors should be fun to watch, but really, they have almost no chance, maybe a conference final. There is probably a 95% chance the NBA champions will come from whoever the top 5 teams are in the NBA preseason. I just looked at NBA preseason rankings through the last 10 years and only the Mavericks at 6 fell out of the top 5 preseason rankings. I couldn't get years prior to 2005, but I'm sure that trend would follow right through to the 80's (whatever definitive power ranking existed back then). I thought the Pistons might be a team that didn't crack the top 5, but they did make the conference final the year before, so they were probably ranked 4th or 5th going into their championship season.
So back to the Raptors.... They are not going to contend for a championship, they are not very young and don't really have that superstar you need to win a finals. The only way I see them having a chance in the next 5 or 6 years is if Bruno is somehow great. Other then that... they're at best, part of the other 25 teams clogging up the league for the top 5.
