I would wait, unless your league starts 2 catchers. there are some high upside guys available even at the end in Napoli, Hernandez, Shoppach that are going later but will get you comparable numbers. You might trade a bit of average but the power numbers and RBI's are there.
Kemp, Gutierrez, Cruz (DL), Soriano, Bay, Abreu
A.Gonzalez, I. Stewart
Halladay, Marcum, Kuroda, B. Anderson (DL), Leake, I. Kennedy, C. Lewis, Pelfrey, C. Richard, Slowey, B. Wagner, H. Street, O. Dotel, J. Axford.
