well i did draft chris young in the 15th round of a 12 team league. i think he's a good candidate for the "best buy" list, as is ray, who was also drafted in the 15th round. both have some promising stats, but IMO young should be your 5-6th SP and ray should be your 2-3rd RP.
i would not recommend drafting Ryan Church, who was also on espn's list. church had a good stretch with the nats last year, but i personally don't think he's worth a slot on anyone's team right now....maybe worth a FA pick later this season if he's hot.
as for the rest of espn's list, i think they're mostly good buys except crawford and myers. they typically get drafted where they should or even sooner.
