As a tall lad myself this rings true to me. In school I was forever being drafted into different sports teams by PE teachers who assumed that just by dint of being so much bigger than my peers that I'd naturally be better than them at football, or rugby, or swimming, or basketball... but nope. Terrible at everything.But it was intimated he was particularly strong, so he should win his fair share of those battles if that was the case, no? I think physically he's very average, just that he's tall so it appears he should be more domineering than he's actually capable of being. He doesn't shy away from those battles though so still provides some nuisance value even if he's unable to bully centre halves in that way some big centre forwards do.
Didn't stop them trying something new each year though. In retrospect I was, in the eyes of many of those teachers, basically a pasty white secondary school Adama Traore, just waiting to be sculpted into something not shit.
