Ron Rivera was asked earlier this week if he thought the Lion's deserved their label of being the NFL's 'dirtiest' team.
True to his defensive roots, Rivera decided to try and put a better spin on it without actually saying he disagreed with it:

Rivera, who played for Detroit defensive coordinator Gunther Cunningham at Cal, said the Lions' defense reflects Cunningham's aggressive philosophy. He wants his players to match that intensity, without losing their cool as they did in the waning moments against Tennessee.

So the Lion's don't lose their cool? Too funny. I love even more what Cunningham said about Rivera's comment:

"I like what he said (this week) about us being a dirty team," Cunningham said. "If there's one coach in the league you want to ask about that, ask him, because he knows. And I was proud of what he said because when you coach against his group, you're going to put your helmet on right."

So Cunningham said "It takes one to know one" in a sense? So they share the bond of the 'Dirty Defensive Coordinator's Guild' or something like that...

You can obviously count it as a compliment as well, that Cunningham will know Rivera coaches his team to bring it and play every bit as tough as the NFL's supposed 'dirtiest' team. We can expect to hear some helmets cracking on Sunday.
