The call

The Vegas setup is everything for a defense: -11.5 at home with Arizona's implied total at 17.0 means a positive game script and a likely pass-heavy, mistake-prone opponent in the second half.
Arizona's line surrenders 3.7 sacks per game and the offense coughs up 1.2 turnovers per game — that's the pressure-plus-takeaway combination that produces DST spike weeks.
The model projects 7.5 points on 2.7 sacks, 0.7 interceptions and just 16.6 points allowed, which grades out DST3 this week — a clear start over any streamer.
Only 48% of leagues have this defense in lineups (crowd rank 12), so it's available in plenty of leagues despite the top-three projection.
