On Monday, the moon did something that probably made Redskins offensive line coach Bill Callahan very proud: it blocked the sun.
That's right — matched up one-on-one with one of the most feared things in space, the moon displayed great technique and a solid anchor, and in turn, treated much of the country to a thrilling solar eclipse. Hopefully, guards, tackles and centers of all ages took note of it, too.
In honor of the momentous event, let's take a look at the five most intimidating players who the 2017 Redskins will be forced to block in the upcoming season. The best part of these battles, by the way? They won't require glasses to view them.
5) Danielle Hunter (Vikings)
Hunter's name isn't as recognizable as the rest of the names on this list, but if he has another year like he did in 2016, it soon will be. The Vikings found themselves a gem in the 2015 third-rounder out of LSU, and the Redskins will see him in Week 10. He had 12.5 sacks as an NFL sophomore after six as a rookie.
4) Joey Bosa (Chargers)
A strange contract battle with the Chargers was followed by a hamstring injury during Bosa's rookie year, but neither of those prevented him from showing out in his first pro season. In just 12 games, the Ohio State product racked up 10.5 sacks, and he should easily surpass that total in a full 16-game season. He'll be the Redskins' problem in Week 14.
3) Aaron Donald (Rams)
Donald is currently staging a contract holdout and hasn't appeared at Rams' training camp. Every team on Los Angeles' schedule surely wouldn't mind if that issue carried into the regular season. Donald can wreck games on his own and has averaged 10 sacks a season through his first three years with team. The powerful defensive tackle is slated to face the Redskins in Week 2; perhaps they'll be lucky enough to avoid him.
2) Khalil Mack (Raiders)
You know you're an elite pass rusher when you record 11 sacks and it's considered a step back. That's the number of takedowns Mack had last season, after 15 the year before. The days of people wondering whether the college competition he faced at Buffalo would hinder his development in the NFL are way behind us. Now, the Burgundy and Gold are left to wonder how they will block him in their Week 3 matchup vs. the Raiders.
1) Von Miller (Broncos)
Miller's been a Pro Bowler in five of the last six seasons and posted 13.5 sacks in 2016 (and that's after not notching one in any of his final four games in the regular season, too). Kirk Cousins, Trent Williams and the rest of the Redskins' offense will have the unenviable task of handling him when the Broncos come to town in Week 16.
