Thunder are a good matchup for Neal. Fisher is one of the few PG slow enough for him.
But, yeah, Neal as a PG has been exposed in these playoffs especially against Clippers. While there are some issue with his ballhandling and court vision, the biggest issue is that he is too heavy to play that position. If Spurs want to continue with Neal as PG next year, they better put him n a diet this summer. Neal with 20lbs less and with some work o his ballhandling and court vision, could be a decent backup PG.
