Josh Willingham has hit in tough parks before, but I think the Oakland coliseum will cap his power at around 18 HR while Morse should approach 25 if he continues to get everyday at-bats. As strange as it sounds, Morse is actually the surer thing in batting average, and with a better lineup surrounding him, Morse should put up better counting stats than Willingham despite the slightly less favorable spot in the batting order.
Between the 2, I'd go with Morse for the reasons stated but I would not feel comfortable rostering either. I would rather have Will Venable, David DeJesus, Lance Berkman, Michael Brantley if you need speed, Luke Scott and Travis Snider to name a few if any of them are available over Morse.
