If he thinks Rams didn't use 3x1 with Watkins alone he's the joke

took less than 5 minutes to pick a game at random, and then find 4 plays in the 1st quarter with that alignment.
He doesn't watch the Rams closely if he doesn't think Rams used this a lot, in fact, during the season I was kind of sick of seeing it, but I knew it's good because it the nasty splits on the trips side make it harder to run man coverage because the WRs can cross, so the defense is forced to switch and you can get favorable matchups doing it.

Benoit, who I generally like, lost points on this one, big time and the proof is in the film.
