49ers Super Bowl 2024 player props guide: Brock Purdy, Brandon Aiyuk

There will be billions of dollars bet on Sunday’s Super Bowl between the San Francisco 49ers and Kansas City Chiefs, from the team to win to how many points will be scored.

But sportsbooks will handle more cash flow in Super Bowl LVIII surrounding props than almost anything else.

One Las Vegas bookmaker estimated that for every traditional Super Bowl wager (against the spread, total and moneyline), there are seven prop bets made.

While it’s always interesting to wager on the color of the celebratory Gatorade bath or how long the national anthem will last, player props are more popular than ever. 

With kickoff just a few days away, we asked two of our betting experts, Sean Treppedi and Tanner McGrath, to share their favorite 49ers bets in Super Bowl LVIII.

Brock Purdy over 12.5 rushing yards (-108, FanDuel)

Purdy is averaging 31 rushing yards per game this postseason, a massive uptick from the 8.9 rushing yards he averaged during the regular season.

He scrambled for 48 yards against the Lions in the NFC title game and 14 yards against the Packers in the divisional round.

The 49ers were trailing for most of those games, and it’s possible that could be the case should their defense be leaky against the 49ers.

As noted here, Purdy has also used his legs when facing teams that like to blitz.

Under defensive coordinator Steve Spagnuolo, the Chiefs like to bring pressure, which could open doors for Purdy to clear 12.5 yards on Sunday. – Treppedi

Brandon Aiyuk Under 4.5 receptions (-130, Caesars)

Aiyuk has been held to exactly three catches in each of the 49ers’ last three games, including both postseason games.

He had 32 yards against the Packers and 68 yards and one score against the Lions.

Things won’t get easier against a tough Chiefs’ defense.

As discussed here, Kansas City leans on man coverage and Aiyuk struggles against that scheme.

Chiefs standout cornerback L’Jarius Sneed, who allowed just a 51.9 percent catch rate this season, could make life difficult for Aiyuk.

The 49ers are more likely to try to beat the Chiefs by rushing the ball against their vulnerable front, which could limit Aiyuk’s chances.

I’m betting on Aiyuk having a quiet game. – McGrath

Christian McCaffrey Under 18.5 rushing attempts (+104, BetRivers)

For as great as McCaffrey has been this season, I’m willing to bet on the under here.

Andy Reid is too good of a coach to simply let the 49ers beat them by riding their best player, even if Kansas City’s rush defense is vulnerable.

The 49ers’ scheme and how they use McCaffrey is also a factor.

Despite his brilliance, McCaffrey has topped this mark in only seven of 18 games (38.9 percent) this season, including just once in the playoffs.

He had 20 rushes against the Lions, but just 17 against the Packers. Before his 20-carry game against Detroit, McCaffrey had not cleared 18.5 carries since Nov. 23.

The 49ers also will surely use Deebo Samuel out of the backfield, which takes away potential carries from CMC.

McCaffrey will instead get the ball as a receiver, which doesn’t help with this prop. – Treppedi
