I think at a minimum they have to bring in 2 more LBs. Sean Lee's contract is up this year and aside from him I think they have to plan for the contingency of LVE getting hurt again.
In an ideal situation LVE remains healthy and one of the newcomers supplants Jaylon Smith as the starter. At this point, I just don't see any strengths in Jaylon's game. He's slow to read and react and he doesn't look nearly as athletic or fast as he once did. Seems like it's a constant struggle for Jaylon to outrace his man to the edge.
He had a few nice plays of that nature back in 2018.....most notably near the goal line against the Texans. But now it seems like any and everybody beats his ass to the edge for extra yardage.
