I'll take the LMA side.

DO IT NOW!!!!! Porter on restriction for several games.

Stick with LMA. I'm not sold on Porter at all right now. Ibaka is also not impressing much right now.

I've been an Otto fan for a couple years, and I just traded him in a similar deal. If they're limiting his minutes severely despite paying him a gazillion dollars, you know the load management and/or nagging injury situation is real. Plus the Bulls are a disaster right now, and the offense seems to consist of little other than LaVine playing hero ball while Markaanen, Coby and Wendell get the scraps. Disastrous teams make for bad end-season situations, too. Get LMA and don't look back.
