There was an article on Pats Pulpit that made a case the Pats were transforming the team for life after Brady.
It's mostly theory and light on examples, but they drafted a running back and receiver in the first round for the first time ever under Belichick.
Maybe you experts can find some other examples, like offensive linemen that are better at run blocking vs pass protection?

It also points out they started out pre-season with a bunch of receivers, but things fell off pretty badly. Josh Gordon became Josh Gordon, went all in on Antonio Brown (big mistake), burned a second on Sanu, and mistakenly traded away Demaryius Tomas as part of the AB debacle.
I think the Sanu trade was mostly a desperate attempt to keep Brady happy after he lost his new binky to mental illness.
I also am of the opinion there is some negative influence from McDaniels. I pray he never becomes HC/GM. He likes his shiny objects too much. I put the Antonio Brown ****-show on him. That seemed like a very un-BB move. Also possibly the last 2 first round draft picks. This all seemed to be one last ditch attempt to wring one more SB run out of the Brady era.
This is where I believe we see the comments from BB about no longer having to build a team around Brady. I read it as no longer having to find veteran receivers that will mesh with the star quarterback, being able to go run heavy on offense, pouring your assets into the defense, and also developing young receivers.
Don't get me wrong and hold the dislikes (how dare I criticize Saint Tom!!!) when you have the GOAT quarterback, you absolutely build the team around him.
Like it or not, this is 100% BB's team now.
