Yeah. Mark Prior. You all can take your always-on-the-DL Pedro. I'll take my staff ace of the future Prior.
I'll glady take a guy who, over the last 7 years, is 112-35 (take a look at that, and just think about it for a second...77 games over .500) with an ERA of 2.21 and 11.33 strikeouts per 9 IP. Prior may one day reach that status, but until then, he's barely qualified to carry Pedro's jock strap.
