One of the peculiar things grungedave pointed out was the fact that Joey Dorsey might not make the roster. The possible addition of Stackhouse would answer the questions. I'm not saying it's happening, but this could be what Morey has lined up. I like Stackhouse but he's getting pretty old.

I have to add fifteen more words so I'm going to put an extra sentence here just to fill up the space.
