I wouldn't simply dismiss the possibility that Seattle resigns Richardson.
Seattle as a franchise does a good job of modeling their roster. Both for the immediate season and for the next two seasons.
Remember, Avril and Bennett are getting on in age. Bennett is now 31 and will be 32 this season. Avril is 31 and will be 32 come draft day next year.
Now that's not 'too' old. These players still have years left to contribute. But it is getting on in years. When we added Frank Clark, I immediately felt like he was going to be Avril's replacement once Cliff's contract expires. And two years into his career, that seems even more likely.
Richardson is now 26 and will be 27 this season. It's not out of the realm of possibility that Richardson is the succession plan for Bennett. We've seen it in a microcosm with the cuts and trades Seattle made this year. When we deep dive into these moves, there is an indelible, overarching theme: Club control. The guys we let go were all either UFAs in 2018 -- or guys with contracts set to be 2018 cap casualties.
And this move also echoes what we've seen Seattle pursue as far as UFA signees or trades. Getting guys in their 25-27 years of age. Players with 4-5 prime seasons ahead of them. We've paid handsomely for them (contract, draft picks or both). And we've also conspicuously not pursued players who generally don't fit this age criteria. About the only one we have pursued outside this range has been TJ Lang this year. But even then he was 29. And an offensive lineman who generally play well into their early thirties.
The point is, I see this deal today and I'm immediately thinking that Seattle is looking two years ahead already. Avril's deal goes through 2018. But if Seattle were to release him, it'd only invoke 500k in dead money. Granting 7.5M in cap space.
That move alone could be allocated to Sheldon in 2018. Putting Seattle in the 15M+ range. That would not preclude Seattle from extending Clark in 2018 -- but would require some back ending of that contract to make the cap value square.
Richardson is the kind of player (interior pass rusher) and age that we've seen Seattle pursue and retain. If Sheldon plays in such a fashion to warrant an 18M contract -- I'm not even convinced Seattle wouldn't be the one to pay it.
Look at the guys we've added. Delano Hill is Kam's mirror (although Kam is singularly unique). Griffin is being groomed to be Sherman's replacement. There is no hope to replace Thomas. But Thomas is 28. Won't be 29 until next offseason.
Seattle is a team already in transition. It's very early yet. And there is no assurance these moves this year will be sufficient. But the moves themselves already belie the long term strategy of the club. We're in it for the now. But these moves also dovetail nicely into a long term strategy where today's foundation players eventually need replacing.
EDIT: It should be noted too, that Malik McDowell was the kind of player to echo this thinking. He is physically a mirror to Bennett too. So it's not even unlikely that Seattle was going into this draft thinking about life after Bennett.
