2033,
but the new buyers after the Holts sell will indeed have brain cells and easily pay the penalty to break the lease and relocate. The Sonics broke a lease to relocate, too, and they played in a city that actually cared. You didn't see empty seats in the lower decks in the 3rd quarter in Seattle because they were out getting Starbucks, huh? But San Antonio and Whatabooger, on the other hand...

. Seattle has arguably the loudest fans in sports, see CenturyLink Field.
San Antonio has nonchalant fat mexican s who mostly just care about booze and food and who's ing who tonight. Sports are secondary... it's like the college fraternity culture with regards to college football. Sure the game is all ok or whatever, but the real story is who's prepping the house for the rage fest tonight! Who's buying the roofies for when the chicks get in, etc.
Mark my words. San Antonio will NOT support a perennially losing team like, say, the Kings over the past 13 years or the Bobcats of the late 2000s or the Browns of the NFL. Should they fall to the 20-25 win range that represents the NBA's cellar, the average attendance will fall to roughly 4,000 mostly in the mid and upper decks. The team will have to be sold. And relocated. And the taxpayers will like it. Prices will go down in SA, and all will be well again. And we'll still always have the legacy of George Gervin, David Robinson, Manu, TP9, and most importantly... the GOAT, TD.
