Jarren needs to leave and Tate should go back to the WR room. In both cases, it's what's best for themselves and the program. I still believe Tate can be an effective slot receiver, or I'd at least like to see him give it a go. It doesn't seem likely that he has a future in football as a QB, but he does have a build and athleticism for the slot IMO.
Jarren is just too much drama and immaturity. Sometimes, the best thing you can do is go to a new environment and reinvent yourself. I believe that's the best thing for Jarren and I wish him well.
