The next great question in my mind is if Flores can establish an offensive identity. It wasn't always pretty for Belicheck and Brady....it took a good 3 or 4 yrs before they landed on this formula that worked. It looks like Flores is going to lean on Gailey to help develop that with Tua. With the benefit of hindsight it seems clear that was the plan all along.
I don't view Tua as one of these transcendent talents like Luck, Rodgers, or Mahomes. To me hes more Brady or Brees where its easier to see how it could fail that how it will succeed. Even though there's a whole lot of talent in this receiving core I don't see that anchor, and they'll have to find or develop that player that meshes with his playing style. Manning had Harrison, Brady had Welker, Brees Colston. That and the cerebral core of the offensive line, typically a good center that can collaborate on the line calls, seem to me to both be vital in the young QB's development.
Even though the defense was terrible last year you could see signs that Flores has a pretty good idea what hes doing on that front.
