Just looked at your RPs again, and you might want to try strengtheniing your closers too, either by adding a closer or by upgrading. Rhodes is unproven AND having a horrible spring, and Izzy always seems to get hurt for part of the season. Both of them will still end up giving you decent numbers by the end of the year, but adding a 3rd closer would be a solid idea. WOrrell, obviously, won't cut it. But if he has any other solid closers, look into it. Chavez and Tejada for Mussina and Gagne/Wagner/Smoltz? I'd do that.
If this other manager drafted Worrell, odds are he forgot about the move to the Phils and is trying to correct his mistake - by finding someone else as stupid as he was. I doubt he was doing it to insult you, but you can't blame a guy for trying to get a good deal for his team. Doesn't mean you have to fall for it.
