You could easily argue Bill needs Tom just as much. You can always throw in hypothetical situations saying this player would do this or that in whatever situation. I dont like basing arguments off of that. Its really unfair to everything Brady has accomplished to say its all Bill. Have you seen Bill win any Superbowls with someone else under center? So there's no way to know otherwise. The way I look at it is they need each other and should be appreciated equally as a player and coach.
That's a fair point. Certain QB/coach combos just tear up the league together. They play off of each others strengths and it's amazing to watch. Even though they've been working with each other for years, the offense has changed and evolved numerous times. From run-oriented, safe, move-the chains... to a record-setting, bomb it to Randy juggernaut...to dual-TEs & ball control... to "OK Tom, do work with these random dudes."
People can say what they want about Bill and Tom being together, but it's not like they're running the same stuff from 2001 out there. 9 AFC Championship games in 11 years shows just how good these dudes are. Adapting, evolving, and continuing to win.
