It is a futile endeavor to try to compare Buxton to Hicks. Buxton has significantly more upside and a better skill set then Hicks did coming out of HS.
I understand how everyone wants to find some Ace pitcher ASAP because the Twins currently lack in SP, but in the draft you always draft for talent this high and not for need, especially since the majority of these players won't even be big parts of your major league club for 3+ years. Heck even our minor league OF depth has taken a big hit this year, the only top OF prospect pulling his weight is Arcia. Hicks/Benson/Morales etc all have looked less than stellar (and thats being nice!)
None of the arms this year jump out as anything close to the Bauer types we saw last year, the Twins will have plenty of chances to draft arms with all there comp picks and high 2nd round pick. At this point you gotta go with Buxton IMO, and we should feel lucky as most people view him as the overall top talent in the draft.
