Lions DC warns Ricky Williams to watch it

I don't know if it's ever a good idea to upset a hothead named Gunther.

Ricky Williams has been alerted.

Detroit Lions defensive coordinator Gunther Cunningham has delivered a public warning to Williams over what the coach believes to be illegal crackback blocks. The Lions will play the Miami Dolphins on Sunday.

"Ricky Williams looks as good as ever,'' Cunningham said while discussing the Wildcat package. "All I can say to Ricky Williams -- and I want him to know this -- if he hits one of our [defensive backs] in the back on a crack block, then I'm coming on the field. I mean, he's had a couple of knockouts, but they've been not legal. I'll just put it at that.''
