NBA Stud Stephen Jackson -- The Dallas Cowboys Need a BETTER COACH!!!

Jerry Jones needs to 86 Jason Garrett's ass and replace him with a TOUGHER head coach, so says Dallas Cowboys superfan (and NBA stud) Stephen Jackson.

The L.A. Clippers small forward (who's from Houston) was rockin' his Cowboys hat out in L.A. last night when we asked about the state of America's Team ... and it was obvious, dude's bummed out about the injury to Tony Romo.

"IT SUCKS," Jackson said.

But when we asked if it's time to drop the head coach, Jackson had some very interesting thoughts ... telling us he thinks Garrett is just too soft to run the Cowboys.
