He's a great #2. He's not the ace of a WS contender. Someone will really overpay for him. Hope it's not the Sox.
I grew up with Clemens leading the staff. Pedro was even better after taking the reigns. Even Schill at least had the attitude of an ace after 04. Since then, the staff has desperately needed a stopper like them. Lester/Beckett/Hamels/Cain/etc are great pitchers, but not true aces. None of them are leaders, either with ability or stature.
