The St. Louis Rams had a phenomenal draft thanks to the luxury of owning two top-15 selections, but even after the draft reaches an end, the rookie additions do not end.
The signing of undrafted rookie free agents is one of the more underrated offseason activities, and it's certainly something the Rams take advantage of every year.
Last year alone, the Rams added two capable rookie free-agent linebackers in Ray Ray Armstrong and Daren Bates, along with running back Benny Cunningham and safety Cody Davis. All four players made contributions in 2013.
Clearly, adding undrafted players is more than a formality. It's a chance to upgrade the roster without making a major investment.
This article will cover St. Louis' 2014 undrafted rookie class and provide a grade for each signing.
