Blake Griffin -- Mark Cuban Won't Hate DeAndre Forever

"Time heals all wounds" ... even in the NBA ... so says Blake Griffin who tells TMZ Sports he's confident Mark Cuban and DeAndre Jordan will find a way to squash their beef.

Of course, Blake's a HUGE part of the Cuban vs. DeAndre rift -- having jetted from his Hawaiian vacation to Jordan's home to convince D.J. to back out of his deal with the Mavs and resign with the Clippers.

So, now ... with Jordan in Cuban's dog house ... we had to ask if there's any hope of repairing their relationship.
