They went 12-4 last year as ugly as it was to watch at times, but yes, that is a bad year with Tom Brady. Why did they have a bad year by their standards? One of the main reasons is BB hasn't drafted particularly well the last 6-7 years. Took Nkeal Harry over AJ Brown and DK Metcalf. Took Sony Michel 1st rd. Long list of draft misses. The cupboard was bare, Brady had no choice but to dip. BB was able to get rid of guys earlier rather than wait for the decline, well Brady flipped the script and did that to them. BB hasn't drafted a non-OL that you would call "elite" probably since 2012.
Their best receiver was a 34 year old slot receiver that hasn't been able to stay healthy for years now and body was clearly breaking dwn as well as a 1st rd pick WR (in a loaded WR draft) that looks like a bust. No pass catching tight end on the roster. Even if Cam isn't the answer, deck was stacked against him. Is he past his prime? Sure, but doesn't excuse getting run up and down the field by equally injury ravaged teams like SF, Buffalo and Denver if we're talking about legends of the highest pedigree here. There is going to be some nitpicking.
How is the debate Brady w/ avg coach vs BB w/ elite QB? So Brady gets Jason Garrett and Belichick gets Aaron Rodgers? Umm, yeah I guess that would be favorable to BB.
How about Brady + Mike Zimmer vs BB + Matt Stafford or Jared Goff...That's a boat race to me. And even a Goff/Stafford isn't always as easy to find as it seems, ask the other teams in the AFC East. It is remarkable how long any of them went without a solid QB during the NE run.
Would BB crush with another legend QB like Peyton Manning? Yeah, sure. Because that guy would also be more important than him just like Brady was.
As far as Tampa chances this year go.... They're top 5 in SB futures right now and top 2 in the NFC. The Tom in Tompa must be doing something right for a team that hasn't won a playoff game since the night Jimmy Kimmel live made its debut (2003)
I guess we'll see when NE is top 2 in their conf and top 5 in SB futures again. Hopefully sooner than later but it may not be the quickest road back because of the challenges I've highlighted.
