I don’t know about discount but I feel your opinion of his value is inflated.
He had 11.5 sacks last year after 4 in his first 2 seasons.
Last year he played 38% of the snaps (374) on defense and played 30 and 31% the 2 previous years.
He had 6 of those 11.5 sacks in 2 games (Indy and az) and 9 in a 5 game stretch.
Who will break the bank for a guy who plays 22 snaps a game, had a 5 game run of good sack numbers and otherwise has a career total of 6.5 sacks in 31 games?
If he wants a contract now it should be based upon being a part time player who had one good month rushing the QB in 3 years.
If he expects more than that, he better play like that greatest month of his life consistently this year and/or develop other skills to earn more playing time.
