He looks that way because he is the most decisive and active of the group. He needs help.
We need more LBs who can diagnose quickly be decisive in attacking the play, show quick ability to recover quickly from misdirection and pursue like hell with abandon.
I will say there were a couple of plays where either Jaylon is either jogging or his injury has left him with no wheels left. Either possibility is not a good result for the Cowboys.
Jaylon has to pick up his game while LVE is out, and lead this team by example and make some splash plays. If he doesn't then I am looking to Thomas to pick up the flag and lead.
