As I see players like Jon Busch and Jason Kreis playing already after blowing out knees at around the same time last year as Mulrooney, I have gotten curious why Mulrooney's rehab seems to be taking considerably longer than these players. Is it: -original injury much worse? -reinjury of knee during rehab? -knee not responding to rehab as hoped? It's kind of making me nervous. Is there any information on his condition besides "hope to dress by end of April?"
