Austin Rivers got the big ol' stamp of approval from his dad and coach -- with Doc Rivers saying he's cool with the NBA star's brand new $300,000 Ferrari!
As we previously reported, Austin splurged on the Ferrari F12Berlinetta right around the time he inked his brand new $35 MILLION contract with the Clippers last month.
So, when we saw Doc at Craig's in L.A. Monday night -- we asked if he was worried about his son/star player behind the wheel of a car with a top speed of over 200 MPH!!
We also asked about Team USA -- and Doc told us who their biggest competition will be.
