This is interesting since his lack of Ks and inability to miss bats has been a complaint many of us(and national guys) have had on him.
Now, he is trying to do it(im guessing for financial reasons long term"?) and its not working for him as well.
I think it's just as likely that he realizes he's been sucking ass and he is trying to up his game. I'm not sure when that scout saw him, but if what he said is true then it's fixable.
