I'll give you that Brady has had better defenses than Manning, but no way the receivers Brady had in his SB wins are better than what Manning had. Manning had Harrison and Wayne in their primes along with Dallas Clark and an aging but still effective Brandon Stokely. Brady had Troy Brown (who moonlighted as a CB by the way), David Patten, David Givens, and Deion Branch. If you honestly would rather have Brady's receivers than Mannings, you need your head checked.
Edited to add - Manning's postseason record as a starter now stands at a wondrous 9-9. Best quarterback of all-time, my ***!!
