Bohanna and Gallimore seem especially vulnerable to a churn. Maybe Golston and Turpin are seen as expendable and having some trade value.
I was disappointed that Turpin didn't get many snaps on offense last season and I tended to think it was mostly on Moore. But during one of McCarthy's recent press conferences, when asked about Turpin, McCarthy basically said that Turpin needs to learn the playbook before he can play offense. To me, it suggests that last year may have been more on Turpin than Moore. Add to that, the kickoff rules have changed. The Cowboys want to find a way to keep Vaughn active on gameday. So maybe you consider trading Turpin.
