Because he's a solid, durable pitcher. And he's getting the same deal as Lilly, when he's a way better pitcher than Lilly. Please make some attempt to quantify that statement. You're almost guaranteed to get over 190 IP, if not 200, while you'll be lucky to get 170 out of Lilly. Over the past four years Suppan has posted a better average WHIP and average ERA. Lilly has a much higher HR/9 ratio, and a much higher FB% than Suppan. Those two things combined in Wrigley could spell disaster for Lilly. Neither are ace pitchers, but with Suppan you know what you are going to get, and if I had my choice between the two for the same contract, it wouldn't even be a debate for me.
