The part about McClain not playing without any thump or violence was ridiculous. Nolan Nawrocki might be the new Pete Prisco.
There was a post from somebody months ago that heard Ireland say that he preferred Spikes over McClain b/c Spikes was much more physical. So opinions that McClain isn't all that physical are hardly new.
