MIAMI GARDENS — The Miami Dolphins were back on the practice field but newly activated tight end Darren Waller was primarily a spectator. Newly signed edge rusher Matthew Judon, meanwhile, made his Dolphins practice debut and made his presence known.

Did the Dolphins need another pass rusher added to the mix? “You can’t have enough of those guys," says Miami DC Anthony Weaver.

Judon appears to be a deadly serious dude. He played three seasons with the Patriots and the first five seasons of his career with the Ravens. In New England and Baltimore, it's not about fun and games. It's about no days off and toughness and culture and kicking butt on Sundays.
