IMO you're buying low on Holliday and selling high on CC.
CC's workload was absurd last year. Sure he's been a horse these past few seasons but I think its going to catch up to him eventually. I personally think you'll get way more years out of Holliday. CC is a much bigger risk. Being a dynasty you have to give the edge to Holliday here.
Yes the A's lineup is pretty brutal, there's really not chance for them to compete this year so I think Beane flips Holliday sometime after the ASB to a contending team for a huge package young players. Holliday won't be in that Oakland lineup all year. Take my word for it.
Top 10 bat vs. Top 5 SP? I'll always take the bat.
Holliday is my choice.
