Smith isn't an aerial threat in the way Oliver was and BAS seemingly wants to turn defenders and run in behind, for that he needs through balls from midfield. Neither of them match the way we play.
Perhaps our strikers will be more of a threat if someone like Miller can cut crosses back from the byline, of course they have to get in the box first!
BAS and also Edmondsun seem to have score a lot of their goals from wingers getting to the byline and cutting the ball back into the box.
