I always grab SP when the value is right. I usually try to grab the last or second to last guy in his tier. For instance, I grabbed Lackey in the 6th round of my last draft (66th overall & before any of the potential injury reports came out) since he was the last true ace on the board. Johan, Peavy, Beckett, Oswalt, Hamels, Webb, Harang, Kazmir, Bedard, Verlander, Haren & Felix were all taken before I grabbed Lackey. I try to do this all the way down the tier ladder.
