When's the last time a big name free agent "took their talents" to NYC? Jasonn Kidd? He really put them back on the map! Pretty sure the only lure to playing in NYC is getting overpaid by the Yankees. Knicks fans are real. Brooklyn not so much. And yes, I've been to a game there. Worst fans/sporting event I've ever attended.
:Biggs is bitter 
amare stoudemire. he was one of the best pfs in the game at the time. later on tyson chandler. wen he was one of the best defensive bigs in the game. and after all that they traded for melo, so if anything is holding the knicks back from grabbing another big free agent its their wallet.
and be serious, brooklyn fans are the worst fans in ur opinion cuz u been to "a" game? like really? u been to one game and u smack a label on an entire fanbase? if thats how u go about everything then theres honestly no point in goin back nd forth wit u cuz ur not gonna care wat i say, so imma jus dead this exchange rite here.
They clearly overpaid for STAT, I don't think anyone would have came close to the $100M they gave him, and for good reason.
I wouldn't consider Chandler a big name free agent. He was two years removed from a salary dump player. He rose the wave of a nice playoff run.
But yeah, Knicks fans have definitely come out of the woodwork the past couple seasons. For basically the entire decade from 2000-10, they were quiet. Now they get a star or two and have mediocre (at best) success and they are running wild.
MSG is usually a nice atmosphere, but I expect Brooklyn to match it this year, if not surpass it. Nicer arena, better team. Fair weather? Almost certainly. But the same can definitely be said about the Knicks, Yankees, or Giants. The Rangers have the realest fanbase, with the Mets not far behind. NYC is a very large city with many residents from all over the world. Now every all four sports have multiple teams, you are bound to have many fans that simply choose to root for the better team.
I fully expect Brooklyn and New York to be the biggest rivalry in the NBA next season. All four games will be wild and if they meet in the playoffs (which is entirely possible with Nets being a top seed and Knicks in the bottom half), expect fireworks.
