Josh Allen under 38.5 rush yds (-110 at Bet365) Yes, I know Josh Allen runs a ton in the postseason, but this line is too high even considering that. Over his last eight playoff starts, Allen's average rushing yards is 41.3, but his median rushing yards is 36, which is already below this line, and that's despite him rushing an average of nine times per game. The Broncos should be a particularly hard defense to run against for a multitude of reasons. First, they limit QB scrambles, allowing the 4th-fewest QB adjusted scrambles per game, and the 5th-lowest QB adjusted scramble rate. That seems counterintuitive knowing they are a high pressure, man-heavy defense, but my theory is that they are just so quick to the QB that they get more sacks, preventing more scrambles and also causing more throwaways. And in fact, that's the case as the Broncos rank second in QB-adjusted sacks + throwaways, which removes sacks that were the QBs fault, causing a forced sack or throwaway on 12.3% of all dropbacks. Then, when QBs do scramble on Denver it hasn't been easy sledding. The Broncos rank fourth in raw yards per carry allowed on scrambles, and third in both QB-adjusted scramble yards per carry and QB adjusted scramble yards per dropback. We QB adjust these numbers to account for the fact that some teams face a ton of Mall Santas, while others face a ton of rushing QBs. Denver has been in the latter group, facing QBs such as Daniel Jones, Justin Herbert, Jalen Hurts, Jaxson Dart, Patrick Mahomes (twice), Marcus Mariota, and Trevor Lawrence, all of whom have scramble games of at least 44 yard this year, and all but Mariota with a game north of 50 yards. Yet, all year the maximum number of scramble yards Denver allowed in a game was 31 (if we remove Week 18 against Trey Lance with backups playing much of fourth quarter when he scrambled for 47 yards). I'm projecting Allen's average yardage closer to 36 yards, but his median even lower around 33.5. I'd play this below the current lines of 36.5 at DK or FD as well, if you don't have Bet365 available to you.

Christian McCaffrey Longest Rush under 11.5 yards (+104 at FanDuel) Just two weeks ago CMC faced the Seahawks, and I gave out his Longest Rush under 13.5 yards and said I'd even play it below 11.5. Then he went and ran for a longest rush of just 5 yards in that game. Yes, it was on only eight carries, but it followed the bigger trend that has plagued him all year. Against top-13 ranked run defenses, by DVOA, CMC has 134 rushing attempts from at least 12 yards away from the end zone in 10 games. He has exactly 1 carry longer than 11.5 yards. Adding in rushes from at least 10 yards away from the end zone, gives him two more attempts. In those 136 attempts he has just five total rushes hitting double digits, adding in two 11-yard carries and two 10-yard carries. He's now also lost George Kittle who is an excellent run-blocking TE, and has averaged 0.2 yards per carry less in games Kittle has missed. If I liked this line two weeks ago, I have to like it now with two extra games added in against top-13 rush defenses where he failed to produce a run beyond 11.5 yards.

Betting Highlights
Favorite Bet of All-Time
I bet on my favorite driver Kyle Kirkwood at 20-1 to win the Long Beach Grand Prix. I went to the race and watched him win it in person for his first career IndyCar win. It was the first time I watched him race an IndyCar in person, so I'm officially his good luck charm.
