Assist increases the chance of a teammate winning a duel when the player is close to him/her. That's how his MF position is perfect. He's close to almost everyone.

Well if that's the case than both have an equal lucky. Plus, Aoyama's hissatsu will have a like 99% chance of scoring if the opponent doesn't use any hissatsu, while Ichino's chance will be quite low.
