since we're speaking of Lidge in the "Nixon/Drew" thread let me add a more general thought on relief pitching.
Remember the good old days of "bullpen by committee"...circa 2003? Well it just so happens that in 2003, the Sox were lambasted from far and wide about going forth with no proven closer...yet come September they had developed one of the best bullpen's in the league with Embree/Timlin setting up Williamson.
I know its history now, but that trio had not, if I'm not mistaken, given up a playoff run through game 6 of the ALCS...and it was only Grady Little's gaffe, IMO, that cost the Sox a trip to the '03 World Series.
Is it a HUGE benefit to a team to have a premier closer that you have tremendous faith in right out of the gate each season? Absolutely. But In 2003 the Sox DEVELOPED a strong closing situation. In 2004 they had Foulkie, obviously. In 2006 they once again retooled and Paps filled the void. I expect they'll do so again, they're not going to go after starting pitching the way they have without addressing the back end of games.
Whether its a shot at Lidge, Gagne, Speier or some other more creative solution, I expect that hole will be addressed.
