I'm in an AL-only keeper league where it costs a bit extra each year to keep players from year to year and I'm in a quandary about whether or not to trade Andrew Miller.  I have been offered Aaron Hill for him, which would be a slight upgrade from my current SS, Brendan Harris.  But here's the issue - I'd be dealing him to my arch-rival, and I would hate to have Miller starring on his team for several years.  I have had an incredible slew of injuries, so it's tough keeping a minor leaguer on my team for so long (we have 26 players on our roster with 18 starters and eight bench spots).  I've tried trading him to the rest of the league, but no one else in the league has much interest (maybe that's why the other guy and I have dominated the league the last several years :) )  I guess my real question here, is when do you think Miller will get called up to Detroit.  If I think he'll get called up in May or June, I think I'd rather hold on to him.  Other thoughts?
