He's getting minutes on a team so actively trying to lose that the are starting two centers at the same time, one of which can't rebound to save his life even though he is a legit 6'11"(Wagner) and 3 guards, none of which have a TS% over 50%.
Someone had to score in those pathetic lineups. My guess is replace Wagner with just some other scrub guy and that guy is scoring some points just like Wagner.
Danny made the right call. Mo is a bad NBA player. That's why he is getting starter minutes in Orlando.
