I'll be very interested to see if anything comes out about the team rule he broke. I'm guessing that there's good reason behind it.
Maybe it wasn't a serious violation, it could be that he just felt Dareus needed to have a message sent to him.
I like that McDermott is trying to instill some discipline in this team though.
He doesn't seem like a total hard ass dick head who's just going to scream and yell at the players for no real reason either. Or a control freak (Marrone type) who's going to set rules that really make no sense (like what color/type of socks to wear).
From what I can tell he seems understanding and caring, while at the same time not willing to tolerate nonsense.
He seems to be waking that fine line between players coach and disciplinarian pretty well, from what I've seen/heard anyway.
