I just rewatched this video, and one thing that I haven't seen anyone talk about, that I hadn't even thought about because I'm so enamored with the rest of his skill setN is the great anticipation he shows.
There's a few examples in this video, the best one being about 5 or 6 minutes in on a TD pass to Bailey when he curls in front of a safety who's cutting off his route.
The ball was already in the air.
Geno saw it and threw the ball where he knew Bailey would be.
That is Brees like anticipation.
