1st off, I'd call $5 for him in a $200 auction league pretty cheap. He's my 4th starter behind Pedro, Harden, and Schmidt...along with E. Santana, Verlander, and Haren. Used selectively, he fits well.
2nd, 6IP, 1R, 5H, 1BB, 7K's...and yes it was against the Marlins, but half the reason I have Hudson is so I can start him when it looks good. He's no longer an every-start pitcher to me, not someone you count on to anchor your rotation, but I'll take his good starts any day.
3rd, if low-K pitchers are a waste of innings, you wouldn't take a Jose Contreras 2006 stat line so far on your team?
44.2IP, 1.42 ERA, .87 WHIP, but only 21 K's?
