I don't like the idea of drafting a pitcher 2nd overall. The injury risk is just too great unless the prospect is off-the-charts in terms of stuff and command. This class doesn't have any of those guys. Keith Law said the other day that he heard Appel was #1 on the Twins' board, for what it's worth.
Not being a scout or even having seen them play, I can't really compare Correa and Buxton, but the Twins wouldn't be working Correa out for the second time unless they really liked him. He's significantly younger than Buxton and it's harder to find 3rd basemen than outfielders. I'd like to see one of those guys and then a bunch of pitchers- preferably with upside. Stockpiling finesse college guys like Dean, Lanigan, etc., is just pointless. You can always find a 5th starter. Draft raw high schoolers and teach them how to pitch. That's what they pay the minor league instructors and coaches for.
