The St. Louis Rams visit Washington in Week 14, which means the Redskins offensive line is in for a long, grueling Sunday afternoon.
While Williams will have his hands full with the NFL's best pass-rusher Robert Quinn, Moses will draw defensive end and fellow UVA alum Chris Long, who presents plenty of challenges for rookies and veterans alike.
Quinn, a first team All-Pro last season, sacked the quarterback 19 times in 2013. Long has collected 20 sacks in the past two seasons.
To make matters more taxing on the 'Skins O-line, the Rams drafted Pittsburgh defensive tackle Aaron Donald in the first round of this year's draft. Donald will generate his own pass rush, perhaps allowing even more opportunities for Quinn and Long to make plays.
At this point of an NFL season, rookies who are used to playing just 12 games in college could be prone to burning out. It's up to Moses to ensure that the proverbial rookie wall is no obstacle.
