Like all the players on this list, Tremble was drafted under the Matt Rhule regime; Reich’s staff could have a different view of his skill set and ceiling.
Per his discussion of potential "surprise cuts" (all of which are prior draftees) Person seems to think players drafted during Matt Rhule's time as head coach might have a tough time sticking around under Frank Reich.
And yeah, that's logical: different head coach, different criteria and priorities.
Exceptions would be highly drafted guys like Jaycee Horn, Derrick Brown and maybe a few others.
