From what I've seen from him, he's similar to Guyer as far as a corner guy playing CF. I'm glad to see him in RF over Perez (who despite the arm strength-best in organization, lacks speed and takes awful routes). Him, Jackson, and Rundle is quite a defensive OF. Burke is only an avg. runner, so his speed will always hurt as becoming a full-time CF'er. I don't think anyone has said Burke would become a full time CF'er. He is definitely a corner OF, but the comment was made above that he could be a utility OF that could essentially hold is own in CF if called upon. I guess it's not really an objective argument, and there's really no way to prove either way, but I would consider Burke's speed slightly above average for his frame and size. Just looking at the number, his 12 stolen bases aren't anything to write home about, but he's only been thrown out once. 92% isn't bad for a "power/middle-of-the-order" guy. And going back to what Nathan said, what he may lack in speed, he makes up with his routes and arm strength.
