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.

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.
