Despite being the best playmaker in the secondary by seasons end (and that's not saying much), my feeling is that Randall had become enough of a malcontent that Gute didn't want another Martellus type attitude on the team and the issues that could come with that.
Randall's meltdown in the Bears game that got him benched and then kicked off the field for arguing with the coaches was problem enough, but then in an end-of-season interview he was again
calling out Packer coaches. By that time, I think, McCarthy may have had enough of him, and Gute maybe didn't want any more
Peyton Place stuff happening as well.
