Running back Raheem Mostert has emerged as the key cog in the 49ers offense following a record-breaking performance in the NFC Championship Game. With Tevin Coleman's status for Super Bowl 54 [murky](https://profootballtalk.nbcsports.com/2020/01/30/tevin-coleman-remains-limited-in-thursdays-practice/) due to injury, bet on Mostert blowing up the prop market with another huge showing in an offense predicated on the run. Like Mostert in San Francisco, Damien Williams has taken over as the backfield bell cow for Andy Reid's Chiefs late in the season. This means oodles of targets and receptions from MVP quarterback Patrick Mahomes. His past usage stats strenthen that case. __More Super Bowl 54 props:__ [Kelce-Kittle](https://www.betchicago.com/super-bowl-54-prop-bets-odds-kittle-kelce-tight-ends) | [Cross-sport faves](https://www.betchicago.com/super-bowl-54-prop-bets-cross-sport) | [Action report](https://www.betchicago.com/super-bowl-54-props-betting-sharp-action-odds) | [Tyreek tops WRs](https://www.betchicago.com/super-bowl-54-prop-bets-wrs-tyreek-hill-sanders-watkins) Below are a pair of running back props to consider for Super Bowl 54 featuring the duo: ## Total rushing attempts by: Raheem Mostert, OVER 17.5, -110 Mostert rushed 29 times for 220 yards in the NFC title game, the latter the second most in NFL playoff history. He looks to be the feature back again for Super Bowl 54. The other RB1 option, Tevin Coleman, dislocated his shoulder in the championship win and is only cautiously optimistic to suit up on Sunday, with pain and flexibility both [concerns](https://www.mercurynews.com/2020/01/27/49ers-super-bowl-injury-report-coleman-ok-ford-not-100-percent/). Mostert OVER 17.5 rushes oozes value in the prop betting market. Some are concerned the 49ers will fall into a back-and-forth aerial attack with the pass-happy Chiefs and abandon the run or that some new rushing option will emerge and gobble up carries after two weeks of preparation. This will not happen on Sunday, and for many reasons. Firstly, the Chiefs are more vulnerable to the rush than the pass on defense. Including the playoffs, Kansas City allows 4.8 yards per carry, which ranks 27th in the NFL in terms of efficiency. This is an open invitation for opponents to run the ball against the unit. Secondly, and most importantly, the rush is the [keystone](https://www.pressdemocrat.com/sports/9363613-181/grant-cohn-defining-kyle-shanahans?sba=AAS) for coach Kyle Shanahan's aggressive, big-play offense. Running the ball is used to set up long play-action passing attempts. If the rush is ignored, the entire game plan deteriorates. Thirdly, Shanahan's running game is simple, so don't expect any trickery or new faces to take the lion's share of carries. The attack is literally designed around two plays: inside and outside zone running. No draw hand offs, reverses, run-options, or other possibilities. It's RB1 behind a zone-blocking offensive line the majority of the time. The 49ers average 31.2 rushes with Jimmy Garoppolo starting at quarterback. Even in seven games trailing at the half, where one would expect San Fran to resort to more passing to hasten scoring, the team averaged 29.7 carries. ## Total receptions by: Damien Williams, OVER 4.5, +100 Since returning to the starting tailback role in Week 17 following a late-season rib injury, Damien Williams has played on over two-thirds of the Chiefs' snaps, including 97% and 85% in postseason wins over the Texans and Titans. Head coach Andy Reid employed a similar usage pattern with Williams in last year's playoffs, putting the shifty, bruising back on the field for 75% and 79% of plays. With LeSean McCoy seemingly out of the backfield mix and Darwin Thompson all but forgotten in recent weeks, Williams is expected to see plenty of action on Sunday. With defenses typically doubling up on either WR Tyreek Hill or TE Travis Kelce, the sure-handed Williams becomes a solid outlet for Mahomes. When playing on at least 64% of the Chiefs' snaps, Williams has been targeted in the passing game six times or more in eight of 10 games, snagging at least 5 receptions in seven of them. __MORE:__ [NFL betting](https://www.betchicago.com/nfl-betting)
