One of the things that stands out: a possible reason for Kaczur's lucrative (and perhaps baffling?) contract extension. "On the Right you kick with your left foot, on the Left you kick with the right foot. On the Right your outside punch hand is your right and on the Left your outside punch hand is your left. You get the picture where this is going. This why good swing tackles (backups that play both) are paid well and needed desperately for depth." Doesn't hurt that Kaczur can apparently fill in at Guard, too.
