I'm a bit shocked by a few of the placements for Sheets and Rodriguez. If people don't think Sheets will pitch as well as he did last season, then I'd agree, but to drop him in the rankings because of a predicted lack of run support? Wins have the best chance of fluctuating amongst the four categories used in standard 5x5 leagues for starting pitchers. Then there are still K, ERA, and WHIP to contend with. Among the aforementioned starters, Sheets lead everyone in both K and WHIP, and was second only to Peavey in ERA last season.
I also like Rodriguez as much as any of the other three. All four play for playoff contenders, and should see plenty of oppportunities. Only Lidge (14.9) posted a comperable K/9 to Rodriguez (13.2) . Rivera (7.6) and Nathan (11.1) probably won't reach triple digits in punch-outs. Rivera should have the greatest number of save opportunities, but I would think the extra 60 strike-outs Lidge or Rodriguez will post if Rivera hits 50 saves again, something he has done twice in eight years of closing full time, should cancel out or provide a better return than the extra five potential saves. Nathan seems like a clear fourth choice (and that's coming from a Twins fan). He doesn't ring up batters like Lidge or Rodriguez, and doesn't play for a team that will win 100 games like Rivera. Given the choice between Lidge and Rodriguez, I'd lean towards Rodriguez, based on how the Astros overused Lidge last year, and their extreme lack of depth and protection in the bullpen compared to what the Angels will surround Rodriguez with.
