Best Bets for Monday Night Football: Miami Dolphins at Pittsburgh Steelers
Best Bets for Dolphins at Steelers | Jaylen Waddle: Longest Catch – Over 21.5 Yards (-120)
Pittsburgh's defense just keeps giving up massive numbers to WRs, most notably league-highs in receptions (14.1), targets (22.5), and a whopping 171.8 receiving yards per game. This secondary is also getting torched after the catch, surrendering the third-most YAC (60.3) and the sixth-most air yards (111.4) in the league. If that's not enough, the Steelers have allowed a reception of 20+ yards in all but one game this season.
Miami certainly has a capable guy in Waddle, who has logged a catch of over 22.5 yards in nine of his 13 games, including five of his last six. Everything is pointing to a breakout game for Waddle, and it wouldn't be surprising at all to see him rip off another huge gain tonight.
Best Bets for Dolphins at Steelers | Tua Tagovialoa: 200+ Passing Yards (+101)
Dolphins RB Devon Achane was hobbled a bit in last week's win over the Jets, so I'm guessing we'll see his workload dialed back some. That sets the stage for Tagovialoa to have more throwing opportunities, and I've got 200 passing yards in any of his last four games.
I've already talked about Waddle up top, and those same favorable stats carry over to Tua's situation tonight. Basically, only two quarterbacks haven't thrown for 200+ yards against this defense all season, and one of those misnomers just barely missed the mark with 199.
Best Bets for Dolphins at Steelers | Jaylen Warren: Over 14.5 Receiving Yards (-111)
Looking at the odds, there's a good chance the Dolphins might pull off an upset against the Steelers tonight. If that's how things play out, I'd expect Pittsburgh to air it out more, especially late in the game.
The Dolphins are giving up the eighth-most receiving yards per game (36.8) to running backs, and that's even after holding the terrible Jets' backs to a stone-cold zero last week. Before that, Miami let three straight lead backs rack up 20+ receiving yards. They've actually been pretty stout against the run lately, so I think the Steelers will have to get creative to get Warren involved in the offense.
Dolphins at Steelers MNF Picks
- Jaylen Waddle: Longest Catch – Over 21.5 Yards (-120)
- Tua Tagovialoa: 200+ Passing Yards (+101)
- Jaylen Warren: Over 15.5 Receiving Yards (-108)
