It's obiously true that JL's legacy isn't finished, but he has aready been the recipient of a Nagurski Trophy and a Butkus Award.
If he wins another national award this year, I believe he will become the first player to win a major national award in 3 different seasons. That would be extremely impressive.
Personally, I've got Spielman, Gradishar, and Hawk on the first level of Buckeye LB's; and Cousineau, Marek, and Katzenmoyer in the next group, among guys that have completed their careers. But if JL wins another national award this year, I think he'll have to be placed among those in that first group, all that hardware would call for it.
