The Grizzlies have officially announced the signings of Derrick Byars, Melvin Ely and Tony Gaffney. It's confirmation of news we heard about Ely and Gaffney earlier this month. Memphis extended a training camp invitation to Byars this week, but it hadn't been clear whether he accepted. The trio of signees brings the Memphis roster to 18.
Byars also drew interest from the Knicks around the same time he worked out for the Grizzlies this month. He was a second-round draft pick of the Blazers in 2007, but Portland traded him to the Sixers on draft night and Philadelphia cut him in training camp that fall. The 6'7" swingman from Vanderbilt has also been to camp with the Thunder, Bulls and Heat over the years, but he only has a pair of games with the Spurs in 2011/12 on his official NBA resume. Last year he split the season between Caciques de Humacao in Puerto Rico and ALBA of Germany.
Byars, Ely and Gaffney are all presumably on non-guaranteed deals with the Grizzlies, as are Josh Akognon and Willie Reed. The team has 13 fully guaranteed contracts, so it's possible that none of the five camp invitees make the opening-night roster, but it seems like the most impressive of the bunch will remain with Memphis into the regular season.
