This was a completely unexpected run, and wonderful in every possible way:
1) Began season hopeful, but lost Butler, and overcame it.
2) Swept the defending champs.
3) Overcame the meltdown in Portland.
4) The huge comebacks against OKC and Miami.
5) Dirk, Kidd, Marion, Terry, Chandler.
6) Beating a young and extremely talented OKC team that hasn't quite figured out how to win yet.
7) Showing LeBron that winning a title takes more than talent, determination, money, and press conferences. It requires making plays when everyone is watching, and overcoming yourself.
No, I don't think they will repeat. However, I could see a situation like the '95 Rockets, where the regular season won't matter. This is not a team anybody would want to meet in the play-offs.
If the Mavs can't do it again, I would love to see a Finals between OKC and Miami. Harden, Westbrook, and Durant against the Big 3.
One other point - Mario Chalmers is a top quartile point guard, imo. Miami really needs to let him run that offense more.
