What the f*** are you talking about? Flexibility is much more than simply the ability to do the splits. In Vlad's case, it's much more of a problem in his upper body. In his breakout year, Vlad was much better at using the whole field for extra bases (A little bit like Bo, who has much less raw power than Vlad, but is one of the most explosive hitters in the league and you can see it in his ability to adapt to pitches deep into count). Vlad looks like he can only pull for power now. The oppo bombs and doubles feel like they are gone.
