I get so tired of the NFL physical standard for players.

Does Antonio Brown fit the standard for a #1 WR? Nope. But he's the best in the game.
Does Aaron Donald fit the standard for a DE? Nope. But he's the best in the game.
Does Russell Wilson fit the standard for a QB? Nope. But he's one of the best in the game.

On and on it goes.

Size matters but it ought not be the be all end all.
The issue for an NFL QB has SO much more to do with the brain than anything else (assuming the arm is good enough).
