But I don't think that an objective observer would call any of the targetting calls this year "dirty". Nacua's was bogus, IMO. McChesney's was stupid rather than malicious (he met the definition of targetting but caused no harm to the player). I thought Tautu's was the most legit (you just can't come in that high), but not really what I would call "dirty".
So I don't think those three ejections indicate a pattern of dirty play, but it is way too easy for a Ute fan to say "BYU has already had 3 players ejected this year" and spin it as a systemic problem where dirty play is rampant on the team.
