Nate has had 3 out of his 6 seasons where he has shot 39% (!!!) or more from 3 point land.
He just got cut by the Thunder (since they have Westbrook + Maynor) so he will come cheap for a minimum contract.
Just like in Boston he has a Big 3 surrounding him so he won't have to do anything more than shoot 3 pointers, which he can with ease.
Plus he just turned 27, so he is entering his prime physical condition for NBA.
And for the nate hate out there... The Heat just ran with the Corpse of Mike Bibby in the NBA Finals last season, so don't tell me Nate Robinson wouldn't be an upgrade or couldn't learn the Heats system...
