I guess it depends on the game situation, and the way you want to spend you $$$ is different in an OL than in a lot of other kinds of leagues... but if I'm up 1 or 2 runs in the 8th or 9th inning and I'm bringing in my kickass closer to finish things off, I'm much more interested in preventing runs than scoring runs. So, if I can upgrade my defense at 2B/SS/3B or the substitute for my (sometimes) Pete Browning-esque corner OF's (I always, if possible, have a good defensive CF), I see a percentage in doing so. I don't always need to have A+ guys getting + plays, but I certainly want to avoid - plays and errors. Lehner and Foli and their their ilk shouldn't set you back more than 500K tops (a dedicated 2B will run you a bit more)... but, if you are in a league with WW and AAA, if you get lucky on your AAA you can always trade in your bench for offensive or pitching upgrades. As I said in my earlier post, though... I put my money on the field. In an ideal situation, my bench is only there to seal the deal after my starters have won a game. That said, I like to have a good PH handy too.
