Or 7 teams have won championships since '96. And the repeaters on that list (SA, LA, Miami, and even Chicago if you go back to 91-93) have done so with huge roster overhauls. It's not like they had some core group of 8-10 guys there for all their titles. They were reinvented, keeping 1, 2, or 3 pieces.
But I also said (and you bolded) deep playoff run. Hell, Anthony doesn't even have a run like Iverson where he was MVP and lead his team to the Finals. Or even like a young Derek Rose literally carrying his team to the conference finals.
If I'm going to offer a player a max contract, have to give in his to his trade demand, or be the sole team a player demands to play for, he better give more and produce more than Anthony has.
Robert Horry was probably never better than the 3rd best player on any team he ever played for. He won 8 titles on 3 different teams though by being a key piece. He wasn't a superstar (didn't demand money, the ball, or certain circumstances to go play), but was obviously a championship caliber player. Miami doesn't win 3 titles without Udonis Haslem. So no, you don't have to be Dirk or Wade and carry your team to a title to be championship caliber. But any player I give as much money and attention to as Anthony, I would want more for my team than what he has thus far provided.
