I might go with Foulke over Rivera, but I would def. be happy with the Cutter.
How about Smoltz? In one league, Foulke was taken so I was having this same debate in my head except plugging in Smoltz for Foulke.
But then, having Gagne already, I took Beckett when I realized he was still available. Figured he was as risky as Smoltz or Rivera but had the most potential as a young ace.
