Halladay is the favorite, but I don't think he's head and shoulders above the competition. Halladay, Hamels, Lee, Kershaw, and Lincecum all have ERAs between 2.53 (Halladay) and 2.84 (Lee). All have a WHIP between 0.99 (Hamels) and 1.15 (Lincecum). And they all have impressive K rates, Kershaws being the best (9.89) and Hamels being the lowest at 8.11. Lincecum probably gets unfairly downgraded due to his 11-9 record, but everyone else has 13-15 wins. It's a close race.
