If it is only taking the last four weeks into account, I can believe it I guess.
He was much more effective as the season went on. That's understandable, as it was a redshirt rookie situation. In addition to that, 3 of the last 4 games were against teams that weren't very good.
The one metric is the last 4 games. The other, the 6th best run defense grade, was the whole season. I'm not saying that Kwon is anything special, I was just dispelling the myth that all of our linebackers were bad against the run last year.
All linebackers benefit from being kept clean by the defensive line, so maybe with a new defensive scheme we'll see more from our unit.
