My opinion, while it appears easy to think "oh, Telvin is the play", there are a few things to consider.
SLBs are Watson and Reynolds
MLBs are Poz and Thomas
WLBs are Hayes and Telvin
-Poz was playing every down, and was the only LB doing so.
-Hayes was already losing nickle snaps to Telvin. Losing Poz doesn't automatically mean that they both will be playing sub snaps now.
-JT Thomas best attribute, actually, is his coverage. So if he actually gets starter base snaps, he has a shot at a 3-down role.
My guess? I'd imagine Hayes, JT Thomas, and Telvin all end up at about 70% snap range here.
