Doesn't matter. Kraft's the owner. Every move Belichick ever made in his time here, Kraft had to review and decide if he wanted to do it. Even if he had a tendency to say yes, at the end of the day, he was the owner and got the final call. If Belichick wanted something and Kraft said no, Belichick did not have the capability to do it anyways every move Belichick made or wasn't allowed to make came with Kraft's sign off.
And before you say "oh well Bill was successful so any team would have been happy to go along with what he said", the Patriots were a very archaic front office for years in terms of giving the HC both coaching and team building responsibilities. No other owner in the league had allowed that for a long time besides Kraft. Most wanted a modernized NFL front office. Even the current dynasty doesn't do it.
Oh and when every single team in the league had the opportunity to hire Bill Belichick and adopt that model when he became a free agent, the whole league passed. There's one other active owner in the HOF right now, and that HOF owner outright fired a coach who just won two Super Bowls so he could maintain control of the team.
So yeah got a rarity in Kraft who set things up so we could get what we got. He kept the team in this location which would absolutely resulted in none of what happened transpiring, I get you don't live here, but another potential owner in St Louis is not making the hires Kraft did, he fired Carroll despite him not being dreadful because he realized it wasn't going to work and didn't want to wait until the ship sunk like many would, he identified Belichick years in advanced, he went against the league and his peers advice and paid extra for Belichick, he gave Belichick the ability to run the team how he wanted, he covered for Bill when he got in hot water with the owner, he fostered a strong relationship with the new QB which smoothed out a lot of the issues the QB and coach had that kept the ship running, he signed off on Belichick's decisions that he thought were good, he vetoed Belichick trying to move off from Brady once which likely saved a SB for the team. He fired Bill when it was time. He didn't drag out the Mayo mistake, he got Vrabel and allowed the team to come back to success.
At the end of the day, the owner is the most powerful guy in the org. Everything runs through them and they can yes or no to absolutely every single option put in front of them. The Patriots first SB appearance of Kraft's era was before Bill was even a HC. He pretty much instantly impacted and changed the course of the franchise
