Taj Gibson, who was a staple for the Chicago Bulls in the 2010s, may be close to retirement at this point. He spent last season with the Charlotte Hornets, but considering they have not picked him up (and no other team has, either), it seems as though his NBA career could be over.
When with the Bulls, Gibson was a crucial part of their rotation. Though he began his career as a starter, Gibson quickly transitioned into a bench player for Chicago, acting as an essential piece off the pine for the Derrick Rose-led Bulls teams that made plenty of noise in the 2010s.
