Hall, 25, is 6-foot-5 and averaged 14.6 points and 4.2 rebounds for the Westchester Knicks of the G League last season. It was his third straight season with Westchester after going undrafted out of Montana State.
He signed a 10-day deal with the Knicks in December for his lone NBA experience, though he appeared in just one game and received two minutes of action.
Following the expiration of his 10-day deal, he returned to Westchester. A native of Rock Island, Ill., Hall went undrafted in 2019.
An Exhibit 10 contract counts toward the offseason roster of 20, but not toward the regular-season roster unless the player is signed to a standard deal.
