I'm not saying that Erstad is great. He is a better fielder than Youk. Range factor aside, and has better range than Youk, he has insane hands and great footwork. He had much better speed than Youk before his injuries, but I don't know what he's got left in his legs. He can play the OF, including CF. Youk cannot. He's a known quantity with an 11 year major league resume. Youk, on the other hand, may only be the ballplayer that he was in the second half of last year, in which case Erstad would be a nice insurance policy.
