Kepler doesn't seem to like that wall. Not too interested in making a leaping play when close. I don't blame him. I would rather have him not hurt and out of the game(s). He sure looks like he doesn't want to really get it in gear on the chase. Or maybe he is just gliding. Tough play either way.
That certainly is the standard and the tradition. Funny thing about tradition, if you never try something else, you never know that there might be a better, more productive way, to achieve a more consistent goal.
