Don't write off LaVar Ball just yet ... "Shark Tank" star Kevin O'Leary tells TMZ Sports even though things look bleak for the Big Baller Brand, he thinks BBB is simply too big to die.
FYI, LaVar has been the laughing stock of social media this week after pics circulated showing a clearance sale on his once-pricey merchandise at a local volleyball game in L.A.
Plus, his BBB website has been "under construction" for months with no real time table to get back up and running.
