Don’t expect to see a lot of center Josh Harrellson when the Detroit Pistons begin the regular season. If things go according to plan Harrellson will probably only get minutes when foul trouble injury or suspension strikes center Andre Drummond and power forward Greg Monroe. But things don’t always go according to plan and Harrellson 24 has two things the Pistons were looking for — he is young and he can shoot the ball. The Pistons announced the signing today — a two-year deal with a partial guarantee for the first season with a team option for the second season. The Pistons were attracted to the 6-feet-10 275 pounder gives because he provides size in case of an emergency and he is a 32% career three-point shooter.
