After eight days of practicing against their teammates, the Patriots finally had a chance to pop someone in a different colored jersey on Monday.
With their first joint practice with the Redskins in the books, Patriots said it felt good to see a new set of opponents in team drills.
"It's definitely good," Mayo said of this week's setup in Richmond, Virginia. "It breaks up the motonony of camp always hitting our guys so it's always good."
Mayo added: "A lot of these situations are controlled situations, [but] at the same time a lot of these things are things we're just trying out. It's just like practice, but at the same time we're going against a different group of guys. It's good work for us."
For Bill Belichick's defense, it's a chance to test themselves against an offense that may not exactly present the best matchup.
While the Patriots added two physical corners in the offseason in Darrelle Revis and Brandon Browner, the Redskins feature a group of smaller, quicker offensive weapons; receivers DeSean Jackson, Pierre Garcon, Santana Moss and Andre Roberts are all under 6-feet.
"Just to see another team [is good]," Revis said. "We've been going at it for a couple days now as a team and going against our own offense. It's good to see a different offense and try to gauge our defense from there. Go from there and try to get better and improve."
According to reports from the Redskins training camp facilities, Revis allowed one catch to Jackson during Monday's session but otherwise got the best of the burner who was picked up as a free agent by Washington in the offseason.
"Competition kicks in at that time," said Revis, who had never participated in a join practice before Monday. "It might be a couple words out there. At the same time, it's all in good favor. We know the Redskins just like they know us. Some of us are friends with each other and it goes back and forth. It's just competition."
The Patriots will have two more days of competition against Washington before the two teams square off in their first preseason game of the season on Thursday night.
