I think we're witnessing something pretty incredible with Tom Brady. Love him or hate him, the guy is playing at an obnoxiously high level at the age of 38 and it doesn't look like his skill set is deteriorating. The guy has been crushing it for 15 years, winning 4 Super Bowls and is pretty much 2 fluke catches away from winning 6. And with the exception of a couple years with Randy Moss, he hasn't had anything close to the skill players these other guys have had. Do you know who was his running back in 2001? Yeah me neither.
I honestly think all the QBs mentioned are special in their own way and any argument is valid. But Brady is outta control and somehow is still making it look easy.
