Hudson all the way.
Last year Hudson had a season that was even better than Zito's 2002 Cy Young contending season.
Hudson in 2003 -
2.70 ERA, 1.07 WHIP, 162 Ks, 240 IP
Zito in 2002 -
2.75 ERA, 1.18 WHIP, 182 Ks, 229 IP
Hudson's numbers are getting better every year while Zito's numbers last season left a lot to be desired.
