I don't disagree, but all homerism aside, Mahomes is a ridiculous talent. I've been watching football for 30 years, and have seen some of the best ever in person during that time. And the kid is special.
It was seeing this play live, his first ever home game, that made me instantly realize I was watching a generational talent.
I immediately turned to my (then) 10 year old son and said "you may be watching the beginning of one of the great careers in NFL history." It was that damn impressive. And he's done nothing to change my mind since.
We were there for the "no look" pass against Baltimore. The 30 second TD drive to take the 2018 AFC Championship game in to OT. The playoff comebacks, including the 2019 AFCCG. It's been incredible to witness. The only thing I can compare it to is like watching MJ play in Chicago in the early 90s, McGwire breaking the HR record in 1998, and the Greatest Show on Turf Rams in '99. There were a few moments with Pujols after that.
As far as QB play, the only others I've seen live that had that same WOW factor were Warner, Manning and Favre. Brady is up there, but he never just floored me with his talent outside of accuracy and ability to see the whole field. Nothing eye popping from him individually when watching in person.
I'm just happy my son has at least one "magic" sort of sports thing he can say he was there for.
Regardless of the era.
