Marqui Christian joined the Los Angeles Rams off waivers off the Arizona Cardinals, according to a source— Aaron Wilson (@AaronWilson_NFL) September 28, 2016
Here's the corresponding roster move.
Looking at his Draft Profile, he looks like a poor man's Mark Barron. He's a box safety that won the Cliff Harris Award as nation's top small-college defensive player in 2015. Given the Rams recent history with box safeties, it's fair to wonder if Christian will be a S, a hybrid S/LB, or a developmental LB project behind Barron.
There's also gamesmanship to consider here. The Rams play the Cardinals this weekend. There's a chance that this is being done to gain some insight into the Cardinals secondary. We'll see if his small-school accolades can help him impress the coaching staff enough to stick around.
