I watched the first 2 episodes. Two things stood out: the level of Kraft's involvement when it came to replacing Bledsoe, and the fact that Bledsoe took his concerns to Kraft. I was surprised that Kraft got that involved. In retrospect, Bledsoe was such a huge asset that it makes logical sense that Kraft would become that involved, and also that Bledsoe would feel like he'd been betrayed. It's logical unsurprising behavior that nonetheless left me surprised simply because Kraft was forthright that he didn't like the move to Brady, that Bledsoe went and complained to him, that Kraft then went to Belichick with his misgivings and told Belichick that his butt was on the line with the move. I don't want my star QB and owner doing these things, but I well understand that 99.9% of the owners would do exactly this.
Second thing: I'm not sure I trust the filmmakers to provide the proper narrative throughout this story going forward based on their take of the Kosar situation. They made it seem like Belichick had been through the replacing a star QB situation once already and made a mess of it. They made it seem as though Belichick was possibly doing the same thing again, which is what caused concern in New England, replacing a beloved QB, but the 1st time he tried it in Cleveland, he made the wrong decision. It was anything but that. Kosar was a failed QB who never went on to do anything in the league again. The move to Vinny T., which rehabilitated Vinny's career, yielded immediate dividends. They turned from losing seasons and went 9-4, into the playoffs, and even beat Parcells and the Patriots. How could anyone read this as anything but the right move?
If I'm being skeptical, the filmmakers are constructing a story arc of Belichick being involved 4 times in his career in an attempt to replace QBs, with mostly dubious results:
Kosar > Testaverde
Bledsoe > Brady
Brady > Garoppolo
Mac Jones > ?
Let the story tell itself, you don't need to characterize something as the opposite of what it actually was.
I will allow that Cleveland fans and the media, including the ownership of the Browns, hated the move to Testaverde because Kosar was their favorite son. In that respect, it shows what can happen when you have everyone against your move.
