David Montgomery or Tre Tucker: Who Should You Start?

The call

• The projection (12.7 PPR, RB21) is right at the RB2/flex line, so he isn't a bench body — but nothing in the profile screams volume either.
• A 37% snap share and 5% target share are the red flags: he's splitting a backfield (the sheet's own context frames the trade as making Woody Marks better) and gets almost no receiving work, which caps the PPR floor and makes him touchdown-dependent.
• Game script is neutral-to-decent: a 1.5-point spread and a 22.0 implied total point to a close game where the run game stays live, but a 22-point offense doesn't promise many red-zone chances to divide up.
• No injury designation is a plus, though the camp note about limited touches to keep him healthy reinforces that this is a managed workload. If he's confirmed as the goal-line back this week, he's a start; if Marks is handling short-yardage, sit him for a fuller-volume flex.

The call

• Role is locked in: 95% snap share with a 19% target share means he's on the field for everything and sees legitimate volume — that's the reason the model leans start.
• The projection undercuts the usage — 10.0 PPR points at WR50 is replacement-level for a 12-team starting three, so he's a flex play rather than a lineup lock.
• Game script is neutral-to-fine: Vegas has the Raiders as 3-point favorites with a 22.3 implied total, which is a modest scoring environment, not a pass-volume bonanza.
• Tip it toward start if your bench alternative is under 10 projected points or in a worse offense; sit him if you have a clear WR3 with a defined red-zone role.
