This is a telling quote from him when asked about his one-handed catch:
”Nah, because there is more to this game than making plays like that,” Gathers said. “There’s an every-day aspect of it. Coming in, critiquing the blocking, and just being an every-day guy. You can make that catch one day than, shoot, and you don’t make no more catches for two weeks later like that. Coach doesn’t like flash players.”
Now, that could be just lip service and when it doesn't really put in the time and effort to do all the things that are required, but if it is what he truly thinks, there's hope he'll make the roster, either as the 4th TE or forcing them to cut Swaim or Schultz (Jarwin is probably a lock because they kept him from being poached last year).
