The Patriots in year 2 of the rebuild went 10-7 and made the playoffs.
The Seahawks are in year 2 of the rebuild (they were 12-4 in 2020 and 7-10 in 2021) and currently sit at 6-5, or just a half game better than the Patriots.
And Seattle is getting insane, never-ever-expected production out of Geno Smith of all people. He's having a career, magical, never-before seen year from him, at age 32. Nobody saw this coming, not even Pete Carroll.
We have no idea whether that will translate into continual building in year 3 (2023), or if Geno will turn back into the pumpkin that he's always been, which would likely mean them slipping back to 5-7 wins, or if they draft a new QB and start over.
I mean, Seattle is your best argument for a team that can rebuild in 2 years, but even this one is a MASSIVE stretch. And that's basically your only example, while I gave you a bunch showing you that 2-3 year rebuilds aren't even close to the norm.
You're losing this argument. Badly.
How are the Patriots doing in year 3 of the rebuild? Hint, no playoffs. No playoff victories.
What about year 4? Does anyone have confidence having a third person leading the offense for your 3rd year quarterback is going to turn out well?
