"...has also dramatically improved his catch percentage (receptions over targets) from 50 percent in 2015 to 69.2 percent in 2016."

That really does make a big difference. Britt could always make plays but his catch percentage was poor. It does seem like there's a good chemistry with him and Keenum. I recall on Hard Knocks there was a comment about how Keenum and Britt had thrown a lot together over of the offseason.

FootballOutsiders rates Britt 16th among WRs through 4 games. I honestly can't recall the last time a Rams' WR was in their top 25.
