For one thing, he's a pretty good fielder. An excellent baserunner, and a great hitter. i don't think he will ever be a 30 homer guy, but it wouldn't surprise me if he is like another little guy, Adam Eaton, and hits 14 or 15 homers a year. To go along with everything else, that's a pretty good ballplayer.
I think being a good baseball player is occassionally overlooked in the draft, in search of off the charts tools. Teams fool themselves. Baseball is a hard game. Guys can have all the power in the world, if they can't hit, it doesn't matter. This guy can hit, and he can field, and he knows what he's doing on a baseball field. He won't get picked off of second base down 5-0, and then again get picked off of second base 3 days later with 2 on and no out.
From what I've read, it doesn't appear he is on the White Sox radar. I hope they are correct.
If this guy was 4 inches taller and 20 lbs heavier, he's probably the favorite to go #1.
