Brady 2007 and Mahomes 2018 were both great but neither belongs above Brees 2011. Brady could just lob it to Moss. Mahomes had Hill and Kelsey. But Brees did it with seven main guys! Four good-but-not-great WR's along with a good TE and two good RB's.
Warner 1999 was arguably better. Fouts 1979 and Moon 1990 should be on the list.
Ehh, I looked at Moon's best seasons, I didn't think it was top 10 worthy, maybe top 15 or 20. Didn't Brees just "lob it" to Jimmy Graham in 2011? Let's not make it like he was throwing to "Big Lot" wide receivers.
