Prior is just the best very young pitcher.

Pedro is "only" 33 and ought to have several good years left.

I think most of us in PB give a boost to a players value just because of age but sometimes the old guy sticks around more years than the young guy. Look at Clemens. I traded him in 2001 thinking I better get something for him before he retired.

Pedro is still #1 in my book and if I had him I wouldn't trade him for Prior.
