It was announced today by Atlanta Hawks GM Danny Ferry that the Atlanta Hawks have signed Shelvin Mack to a 10-day contract.  The Hawks had roster space for Mack due to the releasing of Jeremy Tyler earlier today.  Mack, the 6'3" second-year guard out of Butler University, was drafted with the 34th overall pick of the 2011 NBA Draft by the Washington Wizards.  Mack spent his rookie season with the Wizards, averaging 3.6 points per game, 2.0 assists per game, and 1.5 rebounds per game.  Prior to the 2012-13 season, the Wizards waived Mack, but after a successful stint with the Maine Red Claws in the NBA D-League, the Wizards re-signed him.  He spent about two weeks back with the Wizards before being waived again, and he rejoined the Red Claws, where he was named a 2013 NBA D-League All-Star.  Later on this year, he played for the Philadelphia 76ers on two 10-day contracts as a backup to NBA All-Star point guard Jrue Holiday.  I am not sure I like this signing by the Hawks, though.  They already have two solid point guards in Jeff Teague and Devin Harris, and with Zaza Pachulia's nagging Achilles injury, I think we needed Tyler more than we need Mack.  However, I wish Mack luck in his future with the Hawks, and I hope he proves me wrong.
