12 team, NL only.  I’ve got Rocket on the bench, and suddenly he has value.  Would you trade a top closer (Isringhausen?) for him.  Am I selling myself short in “only” asking for a closer?

Nothing could be worth having Roger Clemens on your team. Consider it an honor and refuse to deal him for anything.

I’d say go for more than a closer. Depends on what you need right now though in the league.

Think about using this as an opportunity to get that closer you need, plus upgrading at another position (such as Clemens and lesser OF for Isring and better OF).  Clemens’ value should never be higher—there has to be someone in your league that believes he will put up 10 wins and a sub 2.00 ERA the rest of the way.  Take advantage of that guy.
