LA is a pretty big market and the Clips seem to be headed for contention as long as there are no major injuries. Why does he want to go to NY? I would feel bad for the Clippers if he left
Sometimes these guys have deals where certain benefits kick in if they join a more marketable team. LA is a big market but the Clippers are not a big market team, they don't have many fans and are second-fiddle in their own city.
If I remember correctly Lebron had something like this in his Nike contract. These things matter a lot during FA and trade negotiations, as they can bump up a player's salary considerably. I wouldn't be surprised if CP3 could make an extra $20M a year in NY strictly from endorsements.
