Why Bucky Irving

Toss-Up· medium

RB1 and feature back. Elusive one-cut runner with excellent contact balance and pass-game usage.

Irving's 62% snap share keeps him TB's lead back, but Gainwell on passing downs and Tucker at the goal line cap the PPR ceiling at RB25 / 12.4 points.

CIN ranks 26 of 32 against RBs (one of the softer matchups, 0-game sample).
Vegas implies 23.5 team points as 3.5-point underdogs.
Listed RB on the latest depth chart with a 62% snap share in 2025.

The call

He's still the depth-chart RB1 with a 62% snap share and an 11% target share over 10 games, so the volume floor is real — this is a flex-caliber body, not a dart throw.
The committee news is the problem: Gainwell was signed off a 73-catch season to take passing-situation work and Tucker (seven rushing TDs last season) is expected to keep goal-line duty, which squeezes both receptions and touchdowns — the two things that push a PPR back past 12 points.
Matchup grades soft at 26 of 32 vs RBs, but that composite is a 0-game sample with 0.00 confidence, so it can't be the tiebreaker; a 23.5 implied total in a 3.5-point game is only average script.
Tip: if Gainwell's passing-down snaps stay limited early, Irving jumps to a comfortable RB2 start — in an RB-thin 12-team roster, 12.4 projected already beats most waiver flexes.

Why David Montgomery

Toss-Up· low

RB1 and lead back. Powerful downhill runner with contact balance and reliable short-yardage/goal-line role.

RB21 at 12.7 projected clears the 12-team flex bar, but a 37% snap share and 5% target share make him TD-dependent in a coin-flip game.

BUF ranks 20 of 32 against RBs (a middle-of-the-road matchup, 0-game sample).
Vegas implies 22.0 team points as 1.5-point underdogs.
Listed RB on the latest depth chart with a 37% snap share in 2025.

The call

Consensus has him RB21 at 12.7 PPR — inside the range you start as an RB2/flex in a 12-team league, and he carries no injury designation.
The matchup grades 20 of 32 (softest = 32), a mild tilt in his favor, though the 0-game sample means it carries essentially no weight.
Usage is the risk: 37% snaps and a 5% target share mean almost no PPR floor from receiving work — his points come on volume-limited carries and scores.
A 1.5-point spread and 22.0 implied total point to a competitive, non-blowout script, which keeps him on the field but caps the ceiling; a bigger favorite line would make this an easy start.
