He needs to be more decisive. Whether it's driving to his favorite spots, making a move before the double team, etc ... But he also needs to be involved early. The last 2 games he really hasn't been. Against Portland they were running the Parker-LMA two man game. Against GS it was LMA and Diaw in the post abusing the smaller guy. Smart options of course but Leonard is wasted standing on the 3 point line or used strictly as a screener. Run a play for him, get him moving without the ball a little. Some of that is on Leonard himself and some is on Pop.
Last night I think he let the refs get in his head a little too. Something he's avoided most the season.
