These are the "you got to be there" calls but they both sound like roughing to me. I'm more sure about the second one being roughing than the first one but like I said you have to be there, just like trying to describe a block/charge call.
One thing is the wings need to help with this, if they see a player blocked into the kicker they need to tell the R, because the R's responsiblity is the kicker, so he is not watching blocks around the kicker.
Larry, will you be joining us next Fall?
