Tony Montana's rise from everyday thug-for-hire into a drug emperor... The death of Little Foot's mother and his eventual discovery of the "promised land"... Luke Skywalker's slow transformation from Jedi into the Sith Lord...
The San Antonio Spurs are not done, by any means necessary. Yes, they are aging, but I would not consider them old. They are still one of the smartest, most experienced teams out there. To say there are over-the-hill is akin to saying Dane Cook is funny; it's just not true. Remember, people also tagged them as past their primes when Dallas beat them in the semis way back in 2006. Yet, since then, the Spurs have been champions once more and the Mavs' title hopes have clearly been squashed.
As for the Detroit Pistons, the cracks are starting to show themselves. I can't (and won't) say that they are doomed, but for the first time in quite a few years, the franchise as a whole is looking vulnerable. Just this day, Joe Dumars has fired Flip Saunders and openly implied to the public that nobody on the starting five is safe. This is big news for a team that has essentially kept the same starting five for the past 5 years.
The Lakers, on the other hand, have been disspelling the notion that young teams should "pay their dues" first. Although if you have a future Hall-Of-Famer, I think it's a reasonable exception. Kobe Bryant has been playing lights out, and I SERIOUSLY doubt Pierce or Posey can defend him. Hell, all Bowen had to do was guard and Kobe still handed it to Bruce.
Tell me if you recognize these names: Rudy Tomjanovich, Gregg Popovich, Phil Jackson, and Pat Riley. All great coaches, yes, but also the only coaches to have won a championship since 1991. That means the past 18 titles have revolved around just 4 coaches. Stretch that a bit and you see Pat Riley winning two more with Lakers back in the 80's. That in itself is unprecedented.
