Why Isaiah Foskey Over Keion White in the Second Round?

Payton doesn't pick defensive players either .

Dennis tells Payton what he wants to run and the type player he wants at certain positions. He gives him prototypes. He wants 6'4" 285 lb guys that can set the edge.

Give Dennis a tweener like Zach Baun and he tried to play him at linebacker for 4 years for no good reason.
I understand that's DA's prototype.

But I have serious doubts that Payton hired DA and then afterwards found out what prototypes he likes. That seems backwards from how Parcells would operate.
