Three things not being talked about enough from the Redskins' first four games

After the Redskins' first three games of the 2017 season, a post was published to look at developments and players from each of those contests that were being passed over for other storylines (and those posts are here, here and here, in case you need some proof).

The words below are devoted to performing a similar exercise, but instead of looking just at Week 4's mostly-but-not-totally-fun loss in Kansas City, the entire opening quarter of Washington's year will be the focus.

There's been plenty of chatter about Josh Doctson and Jim Tomsula's magical touch with the defensive line so far. But here are three things not being talked about enough four weeks into the Redskins' journey.

1) Ryan Kerrigan continues to be one of the NFL's steadiest defenders

This angle likely isn't getting enough run because of additions like Zach Brown and DJ Swearinger and the impact they've brought, the incredible growth of Matt Ioannidis and the sheer size of Greg Manusky's biceps, along with all the other things going on on the defensive side of the ball.

But the truth is that Ryan Kerrigan is, like always, producing, and the production is, like always, not being appreciated enough.

Through four weeks, No. 91's posted 2.5 sacks, recorded a pick-6 and forced a fumble. That sack number should be bigger, too (one play against the Chiefs stands out) and you'd be smart to bet that he'll finish with more than the 10 he's on pace for right now.

Kerrigan will never bring attention onto himself. That doesn't mean you can't give it to him on your own, though.

2) The red zone is again looking like the dread zone

This point tends to slip through when the Redskins are playing well, but it doesn't when they're slumping. But don't allow the very positive vibes around the Burgundy and Gold distract you from the fact that they still have the red zone blues.

Last season, the 'Skins were 30th in the league when it came to scoring TDs once they breached the 20-yard line. They are again in that slot through 2017's opening four weeks, and their percentage (36.3 percent) is actually worse than 2016's (45.9).

The assumption was that they'd at least return to an average level of performance in the red zone after being horrible in their 8-7-1 campaign. Unfortunately, up to this point, they've just returned to horrible.

3) The otherwordly pain tolerance and fortitude that Trent Williams has 

If Trent Williams had a regular job, the man would never take a sick day or cut out early.

In his squad's opener vs. Philadelphia, Williams was forced to leave due to an ankle injury. He quickly returned. And in his squad's showdown vs. K.C., Williams was forced to leave with a knee injury. He quickly returned.

"It's painful right now," the tackle told NBC Sports Washington's JP Finlay after the Chiefs game. "All that adrenaline is starting to wear off and [I'm] starting to feel exactly how painful it is. But it's worth it, man. I wanted to be there for my team. If I gotta fight through some stuff and have a very trying morning in the next few days, it's worth it."

All NFL players have a high pain tolerance. Offensive linemen, however, carry an even higher threshold. Yet Williams may be in a class of his own. And it's a class where missing more than a few snaps is truly unacceptable, apparently.
