I'm not sure why (game plan, injury, illness or whatever) but Murray failed to score 15 points in 26 of his 78 games this year (counting playoffs). For comparison sake, Booker has been held under 15 points 38 times total since his rookie season (266 games).
There are a few reasons for Murray’s inconsistency:
1. He’s a streaky, albeit still very good, shooter.
2. He doesn’t really get to the line.
3. The offense, which runs at a glacial pace (29th itl) runs through Jokic and didn’t score much (19th itl)
4. He didn’t need to take over much during the regular season because the Nuggets won by feeding Jokic and letting him score and find others.
5. In the playoffs, teams schemed to slow down Jokic and Murray was given the keys. He ran hot from 3 in a few games and racked up lots of fga due to defensive scheming which wasn’t present as much in regular year.
