Brady has the potential to be the best by the end of the year.
Reasons to Believe
Despite Brady's early-season struggles, he is still on pace to throw for over 4,800 yards and 27 touchdowns, a number that will surely be higher at season's end.
The remainder of the schedule looks pretty easy for New England, aside from playing Houston and San Francisco in Weeks 14 and 15.
His QBR is a very good 97.2, and that number will only get better in the coming weeks as Brady takes out his frustration on bad defenses and leads his team into the postseason.
Reasons to doubt
Brady's Patriots are off to a 3-3 start and have lost those three contests by a measly four points.
The three-time Super Bowl winner has not been as sharp as usual and one has to wonder if he now has a propensity for losing these close games he seemingly should win.
Fans are wondering if the Pats' defense can make key stops on the defensive end of the ball late in games.
His stats have not been eye-popping, as he has completed 160-of-243 passes for 1,845 yards, 10 touchdowns and three interceptions.
New England's run game has been strong in the early going, so you have to wonder if offensive coordinator Josh McDaniels is a little timid to put the game totally on Brady's arm.
Brady will not call himself the best unless he wins his fourth Super Bowl ring.
Projected Regular Season Stats: 4,658 passing yards, 35 TD, 9 INT
Team Record: 11-5
Playoffs: Lose in AFC Championship
