Forget John Calipari ... UCLA hoops should offer Earl Watson its head coaching job -- so says ex-Bruins star Ryan Hollins, who tells TMZ Sports, the school "needs to hope" he takes the gig.
Of course, Hollins -- a 4-year contributor for the Bruins from 2002-2006 -- says he'd LOVE to see Cal bolt from the Wildcats to take over the reins in Westwood.
But, the dude says UCLA needs to be honest with itself ... and understand that the Kentucky coaching legend is probably a long shot for the Bruins' vacancy.
