Nice analyses, Riggo, thanx for the effort!
FWIW, I almost took Valentin but settled on Snyder because for a little more cash he's decent both ways, more OB, low DP, will drive in a lot more runs. Molina is cheap w/ tons of extra base hits v. lefties, so he's a bonus platoon my team sorely needs to knock in the slow HR guys when they BB instead (Thome, Dunn), good D and OK backup besides.
Burnitz has always done well for me in hitter parks, often an offensive league leader, can play lf or rf and is not a 4. Also leans slightly left to help w/ all those lefty SPs. Has enough OB that I hope he'll be OK in Shea, tho I don't like his 15-gamer roll and so far he's been injured virtually the whole season. I agree I'd prefer to DH Abreu, but it didn't work out that way, and I don't think his 4 in RF will kill me.
I consider Boone a good choice in any park for defense alone, no injuries and he'll get some hits and knock in some runs wherever he goes...I like Hudson too for value, but he does get injured and you got him!
