With the way these guys train nowadays not like it used to be. Julius Peppers played until he was 38. Not saying Addison is Peppers but he could be at the very least similar to what the Bills had in Jim Jeffcoat when Bruce and Phil were starting.
I could see the concern if his numbers went down the last few years but they haven't his actually been quite consistent getting 9.0 plus sacks the last four seasons.
Rereading the verbage it says up to $9m so there are probably incentives to reach the $9m maybe based on if plays any regular downs or leads league in ST tackles/gets a Pro Bowl etc.
Or maybe Indy or LA to the Chargers. If I were him I'd go to Indy as they seem to have the best team and situation as the AFC South isn't the strongest of divisions. Moreso now that Houston traded away Hopkins.
I see Klein as a two down LB who can also play ST. Solid not great player but considering we have him as much as Collins getting guaranteed not a horrible signing but would have preferred a Jordan Jenkins.
Why? The Redskins got at Terry McLaurin at #76 last year and he produced great stats and this year many WR grade better than him and likely there at 54.
Asking a rookie let alone two rookies WR to make an impact a lot especially when have Brown and Beasley ahead of them in depth chart. Yes, it's wise to build depth but we lack depth in other spots besides WR.
