Teams with lower expectations and records that have no chances of making the playoffs are prone to having increased availability for players floating from franchise to franchise. This strategy has given homes to numerous free agents who needed just one opportunity in the right system.
This is usually the opposite for championship contenders, unless the injury bug is found mid-season. The Dallas Mavericks last season were that team with what felt like every rotational player on the sidelines. Thus, Nico Harrison had Kai Jones, a former LA Clipper and Charlotte Hornet, on a contract, where he averaged almost 22 minutes per game for 12 contests.
