individually, yes the consensus is that they don;t help int he toher categories. BUT, if you are luck enough to get a number of good ones, it almost becomes liek ahving a top three pticher, their cumulative effect is that great. We have four RP spots and Five SP spots. one guy has rivera, smoltz, foulke and isringhausen, and let me tell you the effect they have is immense. I have six relievers like that, as Baez and Kim can also play at SP, and still elave room for my rotations. On a whim I compared my six closers against my starters and basically, kim, gordon, baez, beck, mears and donnelly pitched comprable innings to my number one tandem of zito and schilling. similar IP but the stats across the board ranged from similar to superior. so if you can get a bevy of them, I say it can have a profound effect. but if it means having a gagne paired witha mesa, williams and dejean, I would forgo that. But given my six, adn looking to move up in the rankings, I can say it is paying dividends.
