Fantasy Upside
The Rams chose Mason with the 75th overall pick in the 2014 NFL Draft despite having more pressing needs than running back. Thus, they clearly think highly of the Auburn product who broke Bo Jackson's single-season record while rushing for 1,816 yards as a junior in 2013. Mason is currently competing with Benny Cunningham for touches behind starter Zac Stacy but if either back suffers an injury, the rookie would be thrust into a major role on offense. Mason also offers big-play potential in the passing game and figures to impact the screen game throughout the year.
Fantasy Downside
While there was some chatter early in camp that Mason could compete for a starting job, it turns out that OC Brian Schottenheimer was just using coach speak to motivate the rookie. The fact remains that Stacy is the starter and Cunningham has received the first touches off the bench. Cunningham has done nothing to be unseated as a the No. 2 back in the Rams' offense and Mason has a learn curve as a pass protector after not having to block at Auburn. (He did stonewall a New Orleans defender in Week 1 of the preseason but he needs to prove that he can pass protect on a weekly basis.) All of this limits his potential in 2014.
Bottom Line
Mason is currently our 69th-ranked RB in standard formats and 67th-ranked back in PPR leagues. As of right now he projects more as a change-of-pace back than a solid handcuff for Stacy owners. In fact, Cunningham looks like the better handcuff heading into the season, even though Mason offers a higher ceiling in terms of potential and could eventually earn a bigger role. If you draft Mason as a late-round flier, just keep in mind that you may not see an immediate return on your investment unless there's an injury.
