Aside from the Cardinals, Matsko has coached for the Saints, Giants, Rams, Chiefs and Ravens before spending the last nine seasons with the Panthers. The Panthers have had one of the better rushing attacks of the past decade with 30 consecutive regular season games with at least 100 yards from Week 6 of 2014 to Week 3 of 2016.

Prior to the 2019 season, the Panthers ranked third in rushing (16,982 yards) and second in rushing touchdowns (138) since Matsko joined the team. Four of the top six seasons in rushing average has come with Matsko leading the offensive line, and in 2018, the team led the NFL with a 5.1 rushing average.

The Panthers were a top 10 rushing team in seven of Matsko's nine seasons. If the past is any indicator of what is to come, the Redskins should expect a turnaround on the ground.

3. He brings more Super Bowl experience.

The Redskins and owner Dan Snyder have made it clear they want to bring championship football back to the DMV. They backed that pledge up by hiring Rivera and defensive coordinator Jack Del Rio, who have been to three Super Bowls and won two of them.

You can now add Matsko to that list.

Matsko's fourth NFL coaching stint came with the Rams from 1999-2005 when the team's historic offense -- nicknamed "The Greatest Show On Turf" -- dominated the league and won Super Bowl XXXIV over the Tennessee Titans.

While the team was known for its passing attack with quarterback Kurt Warner and receivers Torry Holt and Isaac Bruce, the Rams also had a suffocating ground game led by Marshall Faulk, who accounted for 1,381 of the team's 2,059 yards for the year. The offensive line also allowed only 33 sacks in that season.

In the six seasons that Matsko was with the Rams, the team advanced to the playoffs four times and had two Super Bowl appearances. He was also with the Panthers when they appeared in Super Bowl 50 after a 15-1 regular season finish in 2015.

4. He gets the best out of his offensive linemen.

There are a handful of trends that have followed Matsko during his career: those teams' rushing attacks are usually among the league's best, and offensive linemen have some of the best years playing under him.

In the 26 seasons Matsko has coached in the NFL, he has helped 10 players receive either All-Pro honors or Pro Bowl selections. Hall of Fame tackle Willie Roaf was his first Pro Bowl player when he was with the Saints. Roaf was selected three times during Matsko's tenure to go with two First-Team All-Pro honors.

Other players that Matsko coached include Hall of Fame tackle Orlando Pace, guard Adam Timmerman, Hall of Fame guard Will Shields and guard Trai Turner. Matt Kalil, who played under Matsko in 2017, had high praise for the coach, saying that Matsko "demands excellence in his offensive line room."
