Mercedes-Benz Stadium hosts the first live football of the summer for both franchises Friday night, and while the scoreboard from this one won’t mean a thing in the standings, plenty of roster spots are on the line. The Broncos arrive off a 14-3 season that ended one win short of the Super Bowl, a gutting AFC Championship loss to the Patriots after Bo Nix went down with a season-ending ankle injury. The Falcons, meanwhile, are trying to build on an 8-9 finish and a four-game winning streak to close last season, hoping new pieces on both sides of the ball push them back into playoff contention in a crowded NFC South. Neither starting quarterback is expected to see much, if any, action tonight — Nix is sitting out entirely and Tua Tagovailoa is only down for a look before giving way to the kids. That makes this one about the names further down the depth chart, and there’s no shortage of them worth watching. Bettors following along can track live lines all night on our NFL odds page.

Why Vegas Isn’t Buying the Under

The total opened at 37.5 and has crept up to 39.5-40.5 depending on the book, with sharp money reportedly pushing the number higher throughout the week. That’s a notable move for a preseason opener, a sign that oddsmakers expect both offenses’ backups and rookies to make plays once the starters clear the sideline. Denver opened as a 3.5-point road favorite and has been bet up as high as -5.5 in some markets, with the moneyline settling around -192 for the Broncos and +160 for the Falcons. Given that Denver is expected to play its QB2 and QB3 for a full half apiece while Atlanta will lean heavily on undrafted and rookie talent behind Tagovailoa, that line movement makes some sense — Denver’s carryover continuity, even without Nix, may simply be deeper than Atlanta’s is right now.

The Kid From Georgia Everyone in Atlanta Is Talking About

Forget the starters — the most buzzed-about player in Falcons camp this summer isn’t Drake London or Bijan Robinson, it’s rookie wide receiver Zachariah Branch. The former Georgia standout has racked up 14 receptions through 11 camp practices, the fourth-most on the roster, and head coach Kevin Stefanski’s staff plans to line him up everywhere: outside, in the slot, even in the backfield on jet-sweep looks. Branch is currently ticketed as the No. 4 receiver behind London, Jahan Dotson and Olamide Zaccheaus, but insiders around the building already sense his snap count climbing fast. Friday marks his first live NFL action, and with Tagovailoa playing a limited role before the rookies take over, this is Branch’s stage to show why Atlanta invested draft capital in him. He won’t be alone — cornerback Avieon Terrell, another rookie getting run at both boundary and slot corner, debuts as well, and Georgia products Charlie Woerner, Cash Jones and Channing Tindall have all turned heads in camp, giving this preseason opener a distinctly Bulldog flavor for the home crowd.

On the other sideline, Denver’s most-watched storyline centers on a full-blown quarterback competition rather than a single rookie. Jarrett Stidham, Denver’s primary backup since 2023, gets the start and the first half, with Sam Ehlinger taking over for the second under new offensive coordinator Davis Webb’s play-calling. Only one of them keeps the QB2 job, and coach Sean Payton has made clear this is a legitimate competition, not a formality. Beyond the quarterbacks, Denver’s coaching staff will be monitoring an unexpected center scramble — with Luke Wattenberg and Alex Forsyth banged up and Michael Deiter lost for the year, journeyman Calvin Throckmorton has been thrust into the starting job — plus a tight wide receiver battle between Pat Bryant and Marvin Mims Jr. for snaps behind Courtland Sutton and Jaylen Waddle. Running back RJ Harvey, working in behind J.K. Dobbins, is another name worth tracking as Denver tries to build out a deeper backfield rotation.

Statistically, this is admittedly thin ice — preseason openers rarely tell you much about the regular season. But roster-bubble battles like Branch versus the incumbent Falcons receivers, or Stidham versus Ehlinger, are settled in exactly these kinds of games. Both coaching staffs have said publicly that competitive battles will be decided largely on padded, live-action performance rather than practice reps, which raises the stakes for every non-starter on the field Friday night. For bettors looking to shop the best number before kickoff, a DraftKings promo code or the Fanatics Sportsbook promo are both worth a look for first-bet offers.

Prediction and Best Bet

With both teams playing backups for the majority of the night and offensive continuity favoring Denver’s deeper, more experienced QB room, expect a game that stays competitive into the fourth quarter behind reserve scoring drives on both sides. Atlanta’s rookie playmakers should produce enough explosive plays to keep this one from turning into a rout, even if Denver’s overall roster depth ultimately wins out.

With the total sitting in the high 30s/low 40s and sharp money already pushing it upward, backing the over lines up with what both coaching staffs are signaling: expanded roles for backup skill players eager to make a case for the 53-man roster, which tends to produce more broken coverages and explosive plays than a game where starters are grinding out clock-controlled drives.
