@CATCH17 is probably the closest in this thread with his assessment of Jaylon.
People get this impression that he's a sideline to sideline speed-backer based on his reputation from Notre Dame. He got much stronger during his rehab, and is now just straight-up violent heading downhill. He seems more straight-linish than before though. The team usually uses him pretty well in that regard - blitz the center, run to the sideline, fill the A gap, trigger downhill on the TE from zone, etc - to where he doesn't have to do much more than sprint downhill and clean someone's clock, and he's darn good at it. But LVE is the guy they put in space on the weak side for a reason.
LVE is just a freak, it's incredible how good he is in the open field. Backs and WRs try to stutter-step him, thinking this 6'4" 260 pound LB won't be able to hang with them and will be forced to commit. But LVE can mirror athletes 50 pounds lighter than him, and when he grabs them they just drop. He makes some VERY difficult stops in space look easy.
The biggest weakness with Jaylon right now is probably man coverage, he seems to be a lot less comfortable when his assignment's not "run/drop to this spot", and good TEs can shake him if they're sent downfield. Watch him vs the Eagles, there were times when Ertz and Goedert took him to task. As a 4-3 Will, LVE basically has no weaknesses IMO.
