Casey, 33, will likely return in a bench role, as injuries have worn him down to the point where he can barely play 60 minutes. A beastly striker in his prime, Casey's presence will aid the development of CJ Sapong and Dzenan Catic.
Brian Carroll should also return in a substitute capacity in 2015. At 33, he's lost a step, but he's a proven winner with the wherewithal to clamp down on attacking movements.
Fred, who is the oldest player on the Union, will serve as a player-coach this season. He appeared in 11 games in 2014, but he should get less run this year.
