Sixers will try to be active in the free agency landscope, but it is not a stacked class, and with a recent report of PG to the sixers being unlikely, their main option is OG Anunoby. Say they don't get him, would they rather spend all that cap on mid level guys, or potentially take a shot on Zach lavine, who you won't have to give real assets for? In this case, just sign and trade Tobi over there, which the Bulls can try to trade at the deadline if he has a good half year. (Maybe make his final year an option).
