No, it points to the fact that's been mentioned: player loyalty to a team, a city, and it's fans is a myth that's been debunked time and time again ever since the beginning of the free-agent era, and especially since the 1980s. Magic and Bird only stayed in their respective cities because the owners practically handed them the checkbook to the franchise, although being already in big-market areas didn't hurt. There are rare exceptions, like Stockton and Malone in Utah, but that's the absolute rarity.
LeBron shouldn't have to hide his feelings. He should have gone out in that press conference yesterday and said "HELL YEAH I'M GONNA BE A KNICK IN 2010! BANK ON IT! NEW YORK CITY, BAYBEE!". Should the Cleveland fans be upset? Why? They know that superstars don't stay in Cleveland. Or Denver. Or Portland. As a matter of fact, I give perhaps 25% odds that the Blazers will be able to keep Oden, Roy, Aldridge, and Rudy together for any amount of time once their original contracts end. There's more money elsewhere, more exposure, more ego opportunities for athletes that have been told since they were little that they were special, that they were above the system, above right/wrong and loyalty. It's all about the Cash. The endorsements. The SportsCenter highlights. The sooner that NBA fans (and pro sports fans in general) get it through their emotional, thick skulls that Seinfeld was right... we are all rooting for laundry, and the players that wear that laundry are just hired guns who are only loyal as long as you, as Rasheed Wallace perfectly put it, "CTC", the better.
