Juking is more being able to break down a defender and make him miss when you are at a stop or coming to a stop.  Point guard type stuff/dancing.  Shiftiness is more just a sudden change in direction.  

 

I don't really know what's better for Yeldon either way.  I'm just saying that if he wants to add power to his game that he needs to bulk up and he has the frame for it.  If he loses too much of his mobility then there's obviously an issue with that.  I don't think that by getting to 235 he would lose too much mobility because it would be muscle added to a thin frame.  Its all an unknown though really.  I know Adrian Peterson wanted to bulk up to over 230, but Childress told him no back in the day.
