Because they don't play to serve a useless player tap ins to try to justify a 50 m purchase price. Just look at the tap ins that he scored and say one premier league forward who would miss them. Even Werner scores ta ins when given the chance. Problem is BJ is so poor that he can rarely ever create a tap win for the guy on the opposite side. All tap ins come from the left and ends up for BJ because of his position. No magic about it.
This is ridiculous analysis, I asked you if tap ins were so easy why isn't everyone else doing it and all you've done is offered a critique of Brennan Johnson's game.
Being a tap in merchant and having a poor all round game isn't mutually exclusive, anticipation and ghosting into the box is a skill as well, if it was so easy then you'd see literally every footballer do the same thing...you don't.
And no Werner does not score tap ins, have you actually watched him play? Lmao
