I am not sure GM's & Coaches get it, not only do you need an accurate QB, who can manage the game and is intelligent, great coaching.. and a well balanced, deep team along with him...
GM's have always leaned toward the "shiny beads theory" of team building, they overpay for player X1, but because player X4 is inept they wind up meandering in mediocrity..
As great as #12 is, he benefits from the environment/team created by BB and his crew..
Short answer is no, after this crew of upper echelon qb's retire the quality will diminish.. unless another team figure out the our secret to success..
