Is "niceties" even a word?
Anyways, Lou was always intensely staring at the field, and if you screwed up your assignment on a play, he'd definitely chew you out, grabbing your face mask and hollering at you.
For a small man, he was definitely intimidating, but his teams at ND were some of the best disciplined ones who didn't shoot themselves in the foot with stupid plays very often.
I'll gladly take that kind of an attitude if it translates to winning.
