BB is the GOAT HC, but not the GOAT GM. He benefits from four things as a GM - catching lightning in a bottle on a QB that he passed up for 6 rounds, said QB taking less money over the years to help sign key free agents, the ability as the GOAT HC to coach up lesser players, and recency bias.
I’d rank the following GMs, in no particular order, over BB...
1. Ozzie Newsome
2. Bobby Beathard
3. George Halas
4. Tex Schramm
5. Bill Walsh
6. Ernie Accorsi
7. George Young
8. **** Haley
9. Ron Wolf
BB would come in somewhere after these. I’m sure there’s probably a few that I’ve forgotten. With the exception of Walsh, all did it without the GOAT at the most important position on the field. Bill also had the advantage of walking into a situation in which some key stalwarts in the first dynasty were already on the team. McGinest, Bruschi, Vinatieri, Ty Law, Ted Johnson, Milloy, and Kevin Faulk. Then they won 3 in 4 years. Following that, even though they had the GOAT in his absolute prime, the team proceeded to go on a 10-year drought between Lombardis thanks in large part to BB’s personnel failures as a GM. The drafts from 2005-2009 were not good. They left the team bereft of young talent while the dynasty defense became long in the tooth. They had to rely on FA signings and trades, which pushed them up against the cap. That shouldn’t happen to a GM that’s considered the GOAT.
Exit Scott Pioli and enter Floyd Reese. Chung, Vollmer, Edelman, McCourty, Gronk, Spikes, Hernandez, Solder, Ridley, Vereen, Jones, Hightower, Collins, Ryan, and Harmon all drafted during that period. These players would form the foundation of the second dynasty. Then Reese departed and we went through a similar dry spell from 2014 to roughly 2018 (although this draft is not looking great as time goes on because neither Wynn nor Sony can stay on the god damn field). This left us in a similar position as the decade from 2004-2014 where we went on a dry spell in championships. Players like Easley, Brown, Richards, Cyrus the Virus, and Rivers saw one flop after another with the team’s top overall picks among other missed throughout each draft. This created holes which then needed to be filled by more expensive FA signings and trades, pushing the team up against the cap this offseason. These dry periods should not happen if one is to be considered the GOAT GM. He also ****yfooted around Brady’s contract, essentially granting him one year deals after another while handing him what has been one of the worst receiving corps in the NFL over the last 3 seasons. Brady then left for Tampa and has enjoyed a great season there. He’s still not done. Again, this shouldn’t happen if you’re the GOAT GM. His personnel decisions concluded with letting the GOAT walk and replacing him with the corpse of Cam Newton to go along with what is basically a JV roster. His greatness as a coach got this team to seven wins they had no business getting to. This was a 3-13, 4-12 roster.
He’s not the GOAT GM. He’s in the top 10-15 simply because he was lucky enough to get Brady all those years ago and had the cap flexibility to bring in some good FA signings, trades, and some boom/bust drafts. He IS, however, the GOAT HC. You won’t get me disputing that. But his failures as a GM quite possibly cost this team more Lombardi trophies from 2004-2014.
