With the 2022 NFL season up and running, our fantasy teams are also competing for points. With the fantasy season back underway, we saw superstar running backs such as Jonathan Taylor and Saquon Barkley put up monster numbers in Week 1.However, there were plenty of guys who weren’t drafted at all but had excellent start to the season. They may not have been drafted into fantasy leagues as we didn’t think they’d play as much as they did, or fans and analysts had them as perennial backups.This means there’s a plethora of running back talent sitting on the waiver wire who could eventually win you your league this season.#5 – Jamaal WilliamsJamaal Williams is a touchdown machine in NFLDespite sitting firmly as the RB2 for the Detroit Lions behind DeAndre Swift, you should go pick up Jamaal Williams if he’s available in your league. As long as he can stay healthy, he’s a touchdown machine, as was displayed by his two goal-line scores in the Lions’ Week 1 loss to the Philadelphia Eagles.Currently available in 46% of leagues, according to thefantasyfootballers.com, Williams can be a solid flex option for you going forward.#4 – Rex BurkheadRex BurkheadMany NFL fans were excited for the debut of Houston Texans rookie running back Dameon Pierce, as it appeared that he had won the starting job for the 2022 season. But if Week 1 is anything to go by, that belongs to veteran Rex Burkhead.Burkhead played 72% of the Texans’ snaps, and had 14 carries for 40 yards as well as a further 30 yards through the air. Given his usage thus far, he’s a great flex option should he be available in your league. But be wary as Pierce may yet become the starter.
