The first point is not outright true in a vacuum. When Houston wants to run, it uses more two TE sets and that’s the games you’ve seen higher target volume from Fells.
The encouraging sign for those interested in considering him is he’s second on the team (behind Fuller) in red zone targets on the season.
As someone who owns both and could only keep one, I chose Everett. I like Fells too but as a Texans fan, seems like Watson is the only consistent about the offense these days. Ask any Hopkins owner. I’m still trying to find a way to get Fells back though as I might easily be wrong here going forward.
