Ben is probably a more exciting player with bigger hops and maybe more of a whip of an arm. Some say he is a bit of a head case and isn't great mentally.
On the other hand Jake hasn't been playing volleyball for very long and continues to improve at an impressive pace. He's more of a finesse player but does mix in some power into his game.
I'm not sure how these two compare defensively. Hopefully both go on to represent BYU with Team USA.
