A Cliff Lee signing would make me optimistic and excited, but very nervous at the same time. He's a very very good pitcher, an ace, but he is older than what I'd like to see them commit to going forward (already 31, and has had some injury issues, including this season). Plus you just know some team like the Angels or Red Sox will decide to get in on him, driving up the price anyway. As far as a rebuild, I don't think it has to be that bad, as long as some pieces are moved this season. If Melvin sits on his hands again like last year, it could end up being a much longer turn around period than any of us want.
