Mavs invited him to training camp. Mavs have one 2 way spot open, which is what he was on in Minnesota. There will likely be another 4 or 5 guys in camp on the same type of deal competing for that last 2 way spot. MW4 has a shot to get it.
If he gets cut I could see him heading overseas or he may try the G League thing again, but he would make better money overseas than in the G League.
