P.J. Tucker's straight-up not having a good time in L.A. ... and somehow, it's gotten worse -- the Clippers forward was just fined a whopping $75,000 for publicly saying he wanted to be traded earlier this month.
Tucker -- who was part of the James Harden deal with the 76ers back in October -- has grown more and more upset with his current team in recent months ... having only played in 12 matchups for the Clips.
It got to the point where Tucker told the media he was ready to pack up his shoe collection and leave town for a new squad .
