As others have said, given the fact that "playoffs" = ".500 team" then sure, the Hawks probably have a playoff roster.
But given that the real question is probably "do the Seahawks have a roster to be in the top 2 or 3 tiers of teams," then no. Not yet. Let's look by position:
QB: solid, middle of the pack, not upper tiers.
RB: Tough to say because of injuries and bad scheme last couple of years. But talent-wise, I think so.
WR: Hell yes
TE: See QB
OL: Not yet. Cross is solid enough, but nothing to get excited about. Lucas' knee is a huge question mark, but the talent is there. There is promising IOL talent, but it's too young (and they haven't played together), so I think this OL is league-average-at-best this season, but could be top-10 by next season at the earliest.
DT: Yep, Williams alone puts them in the top tiers, and with Murphy? Easy call for me.
DE/EDGE: Probably good enough with Mafe/Nwosu to be in the top couple of tiers, but the depth is questionable and I don't see elite talent there to rise much higher.
LB: Who tf knows, but I wouldn't put money on it.
CB: If Woolen gets his mojo back, then yeah. Otherwise, there's Spoon and some decent role players. Top-5 potential, but we'll see what version of Woolen we're getting this season. It could also be just league-average.
S: Uhhh....no
P/K: all hail Dickson
Under the best case scenario—our rookie coaching staff doesn't have growing pangs, Lucas is healthy, Haynes hits the ground running, the coaching unlocks Fant and the RBs, Murphy is DPOY level, Dodson's great season wasn't an aberration, Woolen rebounds, and our safety room holds its own—this team could definitely win a playoff game. But I don't see them challenging SF even in that scenario, at least not this year. I'm bullish on 2025, and especially 2026.
Under the worst case scenario—none of those things above happen—this is a 5-6 win team. Again, this is the worst case scenario.
Under a more realistic scenario—some of those things happen, but not all—I see talent for a .500 team that underperforms a game or two because of early season transition to a new scheme and coaching staff.
