The wins and stats make him slightly above average....ahahah!!
The wins and stats are over-hyped because they come under suspect circumstances.
The wins were generated as a result of being on talented TEAMS, including offensive lines that rarely let him get touched, defenses which were not only talented but were proven to have cheated, and receivers who are skilled at getting open and/or catching the ball, especially later in his career.
The stats are helped by a talented team but also are inflated by Brady's uber-conservative approach. You won't throw many INTs if you don't take many chances, but sometimes those chances are necessary, and the truly great QBs not only take but make those throws in the clutch. You also tend to have super high completion percentages when you throw a lot of screens, checkdowns, and other short throws.
To sum up: The wins are a product of playing on a superior team that would have won with or without him. The stats are inflated by a conservative approach and throwing short stuff.
If you replaced Brady with Peyton Manning on those NE teams, they'd have probably won 8 Super Bowls by now. If you allow Manning to throw uber-conservative like Brady by not trying for long throws or putting stuff into tight windows even though he can and throwing more short stuff, his INTs probably drop quite a bit and he has a completion percentage of 75 or something ridiculous.
You say I don't know anything about football, but you're the one who refuses to look deeper beyond the wins and the stats. If you'd do that, you'd see they are the product of a team and a system rather than the QB who gets all the credit and is therefore over-rated.
