I really like the game script potential setup here for both of them. Um, specifically Mason. Um, I really think that Indie is going to struggle to move the ball against Brian Flores and the Vikings... Jordan Mason, he's been out with a thumb injury, but um, hopefully it seemingly like his conditioning is fine and he'll be ready to handle a large workload... The Colts have the fourth highest opponent zone yard per carry rate, 5.1 yards uh per carry allowed on zone runs... I think Aaron Jones has done enough that he's still going to be like usable, but to me it feels like a split and I think it could trend towards Jordan Mason over the second half of the year.
STACKED’s take
Returning from thumb injury faces ideal matchup with game script and workload trending his way.
Primary bold prediction centers on game script potential against the Vikings, who are 6.5-point favorites and expected to have 60-70+ offensive plays. Mason has been out with a thumb injury but conditioning is fine and he'll be ready for a large workload. The Colts allow 5.1 yards per carry on zone runs (fourth highest), have the seventh worst miss tackle rate on RB runs, and fifth highest yards over expectation allowed per RB run—exactly the type of defense Minnesota's zone-run scheme targets. Compares favorably to Jaylen Warren's success against this defense, with Mason excellent at avoiding tackles and creating yards after contact. Vikings offense trending up with Kyler Murray's best game of the season, and they're getting Hawkinson and Addison back, creating touchdown opportunities. Workload split expected to trend toward Mason over the second half of the year; Aaron Jones cannot sustain his current volume. Minnesota views themselves as a contender and ramping up Jordan Mason with two running backs heading into the postseason is paramount for their NFC playoff success.
