I don't think it will be a puppet but he did use the word "comfortable" in describing his reservation with another HC so it will be someone he doesn't feel will rock his boat. This HC to get in his face, that some want, will not be the guy.
But let's examine what we don't like about the present HC, is it because he understands how to deal with Booger? Or is it the sideline gaffes and failure to make adjustments during the games? I do believe Booger is too involved in the team but not on game day, I think he's out of it because he's second guessed too many of Garrett's decisions to the media. He could have called down to the sideline.
This team needs the kind of guy that can manage up and down. He's got to take care of the Joneses and let Booger have his spotlight and instill belief and confidence in his team. That's the real difference when the chips are down and why the Chiefs, Eagles, Patriots and Ravens' players respond, they believe. Pederson even had a bunch of no names believing.
I spent most of my career involved with trying to inspire and motivate salespeople and there was a phrase in our business that fits the NFL or any sports team, I had to "sell the sellers". I believe the players when they say they like and respect Garrett but I do not think they believe in him. They've seen too many instances for him to show his quality and he's failed them.
It's just this simple. Military historians say one of the most amazing events of modern warfare was Patton's march and his strategy at Bastogne and they doubt any other General would have accomplished that. His men would have been questioning the logic and strategy had they not believed in him. That FUBAR phrase was created for most of the high command except for him.
I think that is the answer to why this talent underperformed, they simply lost belief at the critical times. In 2018, they won close games but their belief slipped in 2019 to where they lost them.
Whoever Booger hires, he must sell the team that he's the guy and that's why a HC with some credentials may be necessary. That was the magic that Parcells brought to turn a 5 win team into a 10 win team, they played to their talent level because they believed he would make them better.
