Webb should be solid. Their offense should get a nice boost... 04 AZ HR leaders: Finley 23, Gonzo 17 (with a new arm... I felt so bad watching him sling shot throws from LF), Hillenbrand 15, Scott Hairston(!) 13, D.Bautista 11. They were so bad that they were last in R, HR, RBI. Add Glaus and Green to that offense and they should win at least 25+ more games. If I recall correctly, their bullpen was pretty shot also. Lost were Valverde and Mantei (permanently). Eventually Aquino stepped up and pitched very well and established himself as a sleeper closer.
So that alone should give Webb some Ws. If he gains a little bit more control and not try to fool everyone, then he should return to his 03 level.
