Kirk Cousins bum-rushes Maxx Crosby during Raiders practice

LAS VEGAS — The image of Kirk Cousins as the ultimate Goody Two-shoes preceded his arrival in Las Vegas.Maybe it’s the fact that he now plays for the Raiders.Maybe Sin City is rubbing off on him.

Whatever the reason, Cousins seems to have undergone quite the transformation.And apparently, he’s ready to kick ass and take names if the situation calls for it.Even if the name happens to be Maxx Crosby.The Raiders’ menacing pass rusher got an earful, and nearly a fistful, from the suddenly not-so-mild-mannered Cousins during practice Friday.Crosby, of course, is no shrinking violet himself.He often rules Raiders practices with an iron fist and a booming voice that can be heard from two or three fields away.

Nobody got hurt.And within moments, practice moved on.But Cousins had already made his point.Cross the line and there will be a price to pay.
