I guess it's not polite to ask for "secrets" w/o revealing any, so here are two of mine:
Willie Davis - Had/have him on three teams. Outperformed his season numbers each time. Good D. Great in the leadoff spot.
Willie Smith - $0.71 and I've got him hitting third in a first base platoon hitting over .325 with an OPS hovering around .800 in a 60 mil league. Mucho bang for the buck.
Anyone else in a sharing mood?
