The priority for the Sixers heading into free agency should be to lock up Jimmy Butler with a max contract. I imagine Elton Brand will attempt to do everything in his power to make that happen. But given everything that has transpired in the NBA over the last week, Butler has likely risen to the top of the free agency wish list for many teams, and now there are quite a few threats to steal Butler from Philly. Among them are reportedly the Houston Rockets, according to Brian Smith of the Houston Chronicle.
