Greg Maddux is still a good pitcher, but he has been around for a while and cannot be counted on to top 15 wins.
Seems weird to say that about the guy who is in the midst of the longest consecutive 15-win-season streak in MLB history, but sadly it's true.
And for best rotation, it's a tough call. If Prior was healthy, I'd say the Cubs. Since he's not, I'll say the A's. And that's considering my Yankees bias (I hate them). The big three are awesome (although I'm not so sure about Zito) and adding Redman is icing on the cake. If Harden has the season he looks like he will, they could be far and away the best 5 starters in baseball. I woudln't consider the Astros for a second though. Only Clemens and Oswalt impress me. Miller can be good, but he's not consistent. And Andy Pettitte is thre most over-rated pitcher in baseball - if any 21-game winner from last year should be due for a decline, ir's Pettitte, not Loaiza.
