Why Isaiah Foskey Over Keion White in the Second Round?

I understand DA was defensive coordinator at the time, but two of those picks were on Sean Payton's watch. To be fair.
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.
