I get that the 2021 Dolphins are completely different than the 2001 Patriots and the game is played much differently now. I don't know what "setting up Tua to succeed" ultimately means. More beef and protection is nice. An elite playmaker would be nice. A hot shot rookie RB would be helpful. A generational TE could add a lot of sizzle. And that's if they opt to use early picks on offense.
That being said, in the draft the year Brady first started (ie BEFORE he took over for Bledsoe), NE took Richard Seymour in the first round of the draft followed by Matt Light. That gave NE a starting OL of Light, Mike Compton, Damien Woody, Joe Andruzzi, and Greg Randall. Light would develop into something, as would Woody, but I wouldn't call that a GRADE A front line. The rest of their draft that year was trash.
The following draft they took TE Daniel Graham (who was a decent blocker) followed by Deion Branch. They also hit on David Givens in the 7th round. While I know the Pats and Fins are different, it's not like the Patriots of the day really surrounded Brady with high profile guys. The first two drafts in his era they used only one pick on offense . . . and it was for a blocking TE.
The 3rd draft in the Brady era they spent 4 of their 5 first draft picks on defense and the only offensive player mixed in was WR Bethel Johnson. Once again, they did little to get help for Brady (which would be a common theme for YEARS).
My point being NE didn't really go out of their way to ensure Brady's success by getting him help through the draft. In that era, they didn't even bring in help via free agency. Brady sunk or swim with what he had to work with.
Jumping ahead to 2021, I legitimately wonder what MIA should do to ensure Tua succeeds because I don't know what the really means. IMO, if the Dolphins really have to worry about configuring their team around Tua to ensure his success, that right away almost sounds like they don't fully believe in Tua. I think MIA needs to do whatever they think makes their team better. I think Tua will be Tua and they will be able to access how he does this year regardless.
