I agree, I've always liked Coco, he has a nice personality, but that doesnt win games. I've stated before that i thought WMP could handle Centerfield. He's played there plenty in his career with few errors. I realize it's not the best way to judge defensive worth, especially in the outfield but he is competent.
He is friggin scary with his power, and i dont care if he strikes out as much as he does, he's not going to get any better on the bench, and K's are overrated outs anyways. Occasionally it will matter to hit the sac fly or make some contact, but with his power we should be hoping for the long ball anyway. Besides, who wouldnt take a Dunn on their team?
I say give him a chance, or, in the least, figure out a platoon or something.
