Okay. We're not so far apart in some respects. I get the loyalty to the laundry, it's just not the end game for me. Obviously I'm a huge Brady fan. I honestly feel like he validated everything I invested in the team pre-dynasty. He provided the payoff.
I also believe Belichick was motivated to move the franchise beyond the Brady experience because he selfishly wanted to prove he could win without Brady. I don't feel like Brady considered his legacy in that context... ultimately he would have been content with finishing his career as a Patriot. Belichick wasn't having it, the Krafts weren't going to bat for Brady anymore, and incidentally the roster was crumbling around Brady due to an accumulation of poor drafts by Bill. Brady gave'em one more year for old-times sake but all the principles knew it was over, which makes it all the more bewildering that Belichick had such apparent disregard for the quarterback position 2020.
In the end ironically Belichick prompted a scenario where Brady was the one able to prove he could win without the other, which is something he wouldn't have otherwise set out to do. As it is, Brady finds himself in a highly advantageous position. The NFC South is about to morph into the old AFC East with every team in a reset except for Tampa Bay who almost certainly will find themselves competing in another NFCCG next season.
Meanwhile the Patriots suddenly find themselves looking up at the Bills for sure and probably the Dolphins too. Otherwise the conference featured three wild card teams with 11-5 records, which the Patriots were nowhere near this season. Assuming moderate improvement otherwise with their roster, tell me who their quarterback is and I'll tell you their record. My guess is it'll be Mariota or the like with a 2nd or 3rd rounder being developed behind him.
The Patriots have a long way to go to get past Buffalo. There's no way they're catching KC before 2023 at least. If they go 3-13 like you said in any season then it's over for Belichick. That said, I don't think they'll get any worse than 6-10. I also don't think Belichick will get'em back to the Super Bowl within the remaining window of his coaching career.
Respect brother.
