not anymore. starting next year, the cap won't allow 3 top stars on any team. The Miami heat rule, it's called.
Total cap is 65 million, I believe. The Big 3 are going to get 20 to 22 million EACH. the three of them alone will break the cap. Then you can't afford any decent players around them. Now that everyone from Allen to Haslem to Battier has their titles, they're going to stop leaving $ on the table to play in MIA, and they'll do what Miller did last year, and get rich someplace else.
It won't happen again. Two stars, yes. Two stars and 1-2 realllly good guys, yes. But 3 top guys cannot happen again unless they're willing to take a bigger hit than lebron/wade/bosh did.
