It took a few weeks for Marshawn Lynch to knock the rust off in his return to the NFL last season with the Oakland Raiders. After retiring ahead of the 2016 season, following a year in which he played in just seven games, Lynch needed a bit of time to get back to his bruising ways.

Fortunately, that happened, as he wrapped up the season with 891 rushing yards and seven touchdowns while posting a respectable 4.3 yards per carry. But unfortunately, this didn't translate into the Raiders having success as a team, and their 6-10 record was one of the biggest disappointments in the league.

With Jon Gruden now taking over as the Raiders head coach and Greg Olson taking control of the offense, though, expectations are once again high, especially on that side of the ball. There's reason for optimism across the roster, but specifically when it comes to Lynch, as he's been about as reliable as they come when he plays a full season, or very close to it.

To this point in his career, when Lynch has played 15 or more games in a single season (six times), he's topped 1,000 yards in every season except his most recent with the Silver and Black. In that same scenario, he's also scored at least seven touchdowns in all six seasons.

Which is exactly why the most recent prop bets on Lynch's predicted stats from BetOnline.ag for the 2018 season are so head-scratching.

Rushing Yards: Over/Under 650

Total Touchdowns: Over/Under 5.5

While the Raiders do have Doug Martin, who may steal a few carries and take away some of Lynch's touches, it's hard to envision anyone other than Beast Mode handling the goal line duties. That aspect alone should help get him over the 5.5 touchdown mark.

As for the yardage, when looking at his final five games of the 2017 season, he tallied 434 yards on 84 carries (5.1 yards per carry). If you expand that out through the final eight games, Lynch nearly topped that 650-yard prediction, totaling 625 yards.

While plenty of prop bets on players ahead of the NFL season seem to be right on par, these two released on Lynch don't make much sense. The only potential arguments for Lynch's projections being this low would be that oddsmakers are expecting a big drop-off in production due to age, or a belief that Martin is going to take away a large number of carries.

Regardless of how you look at it, I can't envision Beast Mode not wrapping up his 2018 season by rolling past 650 yards and finding the end zone six or more times.
