Big Baby Davis Says The Clippers Are Done, Blake Griffin Should Join Westbrook

Glen "Big Baby" Davis says your Blake Griffin jersey is about to become a collector's item ... telling TMZ Sports the Lob City era is OVER ... and he knows exactly where Blake should go next.

If you hadn't heard, both Chris Paul and BG opted out of their contracts -- strong signs each man is looking outside of L.A. for the next gig.
