NFL Football Best Bets: Week 10 (2021)

Ryan’s Season Totals

Best Bets: 16-9, Up 858%

Last week brought us a mixed bag, going 1-1 on the weekly plays.

We feel good about our selections this week, finding a few plays where our models match our subjective gut (the “holy grail” for handicappers). Let’s jump right in.

Best Bet #1: Kansas City Chiefs -2.5 (-115) over the Las Vegas Raiders

The once “ultra-reliable” Pat Mahomes/Andy Reid-led Chiefs have frustrated prognosticators throughout the year. However, they are still the Chiefs, and still have a QB that can/should win any game he plays

The apparent issues with the club comes down to the impression that Pat Mahomes is “down” this season. And when you look at traditional stats, and even some surface-level advanced numbers, it’s fair to reach that conclusion. Here’s how his numbers compare to last season’s:

However, when you look deeper in the advanced stats, Mahomes isn’t as “down”, as much as it is his performance when pressured (a very volatile stat), is “down”. Take a look at the table below:

As you can see, when ONLY looking at performance with a clean pocket, not much has changed from the 2020 Mahomes to the 2021 Mahomes. And note that performance from a clean pocket is far more predictive than performance from a pressured pocket.

Now let’s look at what’s happened when pressured (the less stable metric):

When comparing the two, 2021 vs. 2020, here is how all that breaks down in terms of “how pressure affected Mahomes performance THIS year, vs. last”:

To summarize, Mahomes is fine, and the same elite QB we’ve known. His overall stats are simply being affected by a “non-sticky” variable that tends to flatten overtime. And knowing that “the Chiefs are still the Chiefs”, and the only issue has been Mahomes when pressured, looking at PFF Rankings that have the Raiders as the #1 Pass Rushing Unit, may lead you to worry about his performance in this game. We see it a different way:

Using this visual, thanks to our friends at PFF, shows there shouldn’t be MUCH that the Kansas City OL can’t handle, with one exception: Maxx Crosby, PFF’s #2 rated DLE. At first glance, you may worry that Chiefs RT Lucas Niang can’t handle him, given his 59.1 Pass Blocking grade, but much of that grade is bogged down by early year difficulties by a young O-Lineman making his first NFL snaps. The slow learning curve by OL has been a well-documented phenomenon in the analytics community. And this very thing is what we’re seeing with Niang, as the last two weeks he has posted a very respectable 75.1, and 77.4 Pass Pro Grade.

Knowing all this, we feel the issues haunting the Chiefs will either be neutralized by learning curves, or simple variance, that it feels like a gift to get the Chiefs with less than a field goal worth of points.

Bet: Kansas City Chiefs -2.5 (-115)

Best Bet #2: UNDER 45 (-110) points between the Eagles and Broncos

Both teams come into this game pretty close in rank, by both PFF (15h and 16th) and Football Outsiders (20th and 19th) rankings. Yet when you dive a little deeper you find a few interesting advanced matchup splits to consider. To start, Eagles QB is one of only a couple QB’s that year-over-year has shown a consistent better performance vs. zone defenses. This year, according to the SIS Datahub, Hurts has averaged .24 EPA/play vs Zone defenses, but .03 EPA/play vs man. That’s almost an 8x bump to performance vs zone. Yet, the Broncos run one of the most “man-heavy” defenses in the league. 

On the other side, the Eagles defensive identity this season has been: Heavy Middle-Field-Open (MFO, or two safeties split deep, instead of one deep S), and sit back in zone to keep everything in front of them. Well, it turns out Broncos QB Teddy Bridgewater has an unusual split: 56% Success rate vs MFC/Single High Safety looks, but a 45% success rate vs MFO/Double High S looks. This could mean trouble for Teddy and the Broncos offense. Additionally, Teddy has an odd split, performing BETTER when blitzed (44 % vs 57% success rates) than rushed by only 3-4, yet the Eagles don’t blitz (26th most). All of this leads me to believe this may be a defensive ball game.

Bet: UNDER 45 points between the Eagles and Broncos

Best Bet #3: Justin Herbert OVER .5 Interceptions (+105)

To be fair, we have gone to this well a few times this year, with varied success. However, our model is very strong on this selection in week 10, especially given the EV with a +105 bet.

Our model has Justin Herbert at the 3rd most likely QB to throw an interception this week. The reasoning comes down to a few key markers, starting with his archetype (thanks to NFL next gen stats):

Time to Throw Rank20th longest TTT
ADOT Rank25th farthest 
Aggressiveness Rank12th most aggressive
Expected Completion Rank7th highest
+/- Completion Rank24th best

Herbert is a marginally aggressive thrower (into tight windows), that holds on to the ball, yet hasn’t (relatively) chucked it deep. Given that, and a bad CPOE, on its own lends to a likely interception. But when you add in the fact the Vikings come in with a +12 Net Pass Rush Ranking Advantage (see table below thanks to PFF), that pressure aids in a high likelihood interception projection.

LAC Rank201191716159242721101026-12

Finally, when you mix in the Vikings 5th rated coverage unit, you can see a recipe for at least one pick this weekend.

Bet: Justin Herbert OVER .5 Interceptions (+105)
