When the 2021 NFL schedule was released back in May, I was pretty sure that we covered every angle here at CBSSports.com, Keith Kinkaid Women Jersey but apparently we forgot one: Best coaching matchups.Ladies and gentlemen, I present to you the top 10 coaching matchups for the 2021 season. If I've learned one thing from watching the NFL over the years, it's that the che s match that goes on between two coaches can be just as fascinating as the action on the field. If you want to see some expert level che s being played then the 10 games below are the ones that you should circle on your calendar right now, unle s you don't own a calendar, then I would probably just set my phone alarm or tell Siri to remind you. This list only has one rule and that rule is that I decided not to include any divisional coaching matchups. Am I excited to see Pete Carroll vs. Kyle Shanahan? Yes, but that game happens twice a year and if you play a team twice a year, you can't be on this list.Remember, this isn't a list of the top 10 coaches in the NFL, it's a list of the 10 best coaching matchups of 2021. If you'd rather read a list of the top 10 coaches in the NFL, . For everyone else, let's get to the 10 best coaching matchups of the 2021 season. When it comes to making the jump from college football to the NFL, no one has had more succe s than Pete Carroll. After spending nine seasons at USC, NHL Montreal Canadiens Men Jersey Carroll made the move to Seattle in 2010. In his first season with the Seahawks, Carroll took the team to the playoffs, which was impre sive, because Seattle was coming off a 5-11 season in 2009 the year before Carroll arrived. Meyer will certainly be hoping to emulate the succe s that Carroll has had at the NFL level. Basically, this game matches up two of the best college coaches of the past 20 years, except we're getting it in the NFL, and it's going to be exciting to see how things play out. The best part of this is that it will mark the first time that Carroll and Meyer have faced off because they didn't coach against each other at the college level.

This game will be a homecoming for Stefanski, who spent 14 seasons on the Vikings coaching staff before taking the Browns coaching job in 2020. In six of those 14 seasons, Stefanski served under Mike Zimmer and he held multiple titles during that time, including tight ends coach, running backs coach, QB coach and offensive coordinator.Basically, if anyone can figure out how to stop the Browns' high-powered offense, it's probably Zimmer and that's because the Vikings coach knows Stefansk's offense inside and out. ZImmer and Stefanski have an interesting history. Not only did they coach together for six years, but back in 2018, Zimmer refused to give Stefanski permi sion Ben Chiarot Men Jersey when he wanted to interview for the offensive coordinator job. Vikings denied permi sion for Giants to interview and hire their QB coach Kevin Stefanski as their OC, per league source. Stefanski stays in Minnesota, Giants still need an OC. Adam Schefter (@AdamSchefter) You have to think that Stefanski would love to light up Zimmer's defense when the Browns visit Minnesota in Week 4.For the most of the past decade, NFL teams have been hiring offensive-minded head coaches, but that doesn't mean a defensive-minded coach can't find succe s in the NFL and two guys two guys who have bucked the offensive trend are Mike Tomlin and Sean McDermott. Both defensive-minded coaches have been wildly succe sful since being hired. For Tomlin, not only does Noah Juulsen Jersey he already have a Super Bowl win under his belt, but he's never had a losing season during his 14 years in Pittsburgh. On McDermott's end, he's led the Bills to the playoffs in three of his four seasons, which is nearly impo sible to believe when you consider that they had not made the postseason a single time this century before McDermott's hiring in 2017.The fun twist here is that Tomlin and McDermott were once college teammates at William & Mary. Mike Tomlin and Sean McDermott - William and Mary teammates, head coaches of the Pittsburgh Steelers and Buffalo Bills (via ) Jeremy Fowler (@JFowlerESPN) Now, the two former teammates are two of the best coaches in the NFL. These two guys have faced each other twice with the Bills winning both times, so Tomlin will definitely be looking for some revenge in Week 1. This might seem like an odd matchup to have in the top 10, but any time you get two highly succe sful old-school coaches with opposite philosophies facing each other on the field, you have to put it in the top 10. In Week 10, it will be the unstoppable force vs. the immovable object when Arians and his "grip and rip it offense" face Rivera and his brick wall defense.These two coaches faced off against each other in the playoffs last year and Washington gave the Buccaneers all they could handle in a 31-23 lo s where Rivera was forced to start his fourth-string quarterback. Arians and Rivera actually have a long history of coaching against each other in big games. Last year's playoff game marked the third time in seven years that they coached against each other in the postseason and although it might not be a full-fledged coaching rivalry just yet, watching these two coach against each other has been unexpectedly fun in the past and I'm gue sing this game won't be any different.One thing that makes this matchup so fascinating is that McDermott actually got his NFL coaching start under Reid. Antti Niemi Jersey Back in 2001 when Reid was coaching the , he hired McDermott to serve as an a sistant to the head coach. After that, McDermott was steadily promoted over the next few years before being moved up to defensive coordinator in 2009. Overall, McDermott spent 10 years with Reid in Philadelphia, so if anyone can figure out how to stop the Chiefs' offense, it might be the Bills head coach. That being said, being highly familiar with the Chiefs' offense hasn't helped McDermott over the past two years as Buffalo has lost its past two games against Kansas City by an average of 11.5 points per game. Despite that, any time you get one of the best offensive minds in football going up against one of the best defensive minds, it's must-see TV, so I'll definitely be watching.Bill Belichick is arguably the greatest coach in NFL history and one reason he's so good is because no coach in the
