The Seattle move is interesting. I'm not sure they can overtake SF for the division (or New Orleans for the #2 seed) but absolutely I think they're a playoff team.
I would be pretty surprised if 5 of the 6 NFC playoff teams aren't the same this fall with my only swap being able to see the Bucs and Vikings battling out for a spot.
Oh, I absolutely think they can. Both of their head to head games with the Niners in 2019 were nailbiters, and Russell Wilson is annually underrated.
