I liken it to the modern, 6'2ish midfielder. Wasn't a thing until it was. When it finally works, everyone will try it.
The key is abililty.
A gun 6'2 midfielder is great, but if they aren't that talented you are better off with a guy like Merritt. ( or Jack Steven ).
Tall wingers are probably good if they have talent and can get the ball off the deck.
Dylan Roberton was at his best on a HBF , and didn't play tall.
