Yeah, he's scared of getting benched and tries way too hard to get something going. He's solid when starting and he doesn't need to look over his shoulder to see when Monty will yank him.
If Monty ran a more structured rotation between Paul and Payne I think it would help both. Let them split minutes in the 1st, pulling Paul around the 6 minute mark, and letting Payne play the first 5-6 minutes of the 2nd quarter. Repeating that in the 2nd half only inserting Paul after the first 4 minutes of the 4th.
Payne is better as a replacement for Paul, when he's out injured or resting, than anyone else we'd find.
What we need is more of a combo guard like a Jordan Clarkson who can handle the ball, help with playmaking, and create his own shot. That's not Eric Gordon either, whose name has been tossed around a lot. Gordon was that 6-7 years ago but he's almost exclusively a shooter at this point, a grossly overpaid shooter also.
