The Hawks have added former Georgia Tech forward Isma'il Muhammad to their training camp roster, according to Chris Vivlamore of the Atlanta Journal-Consitution (via Twitter). Muhammad is the 19th player under contract for the Hawks.
Muhammad was considered a solid defender and an outstanding dunker during his days at Georgia Tech. The 29-year-old graduated back in 2005, but was in an NBA camp as recently as last December — he was waived by the Bobcats just a few days before the season started.
With 14 players on fully or partially guaranteed contracts in Atlanta, and guys like Damion James and James Anderson expected to compete for the 15th spot, I'd expect Muhammad to be an extra body in camp, rather than a real candidate to earn a roster spot.
