Well yeah, the commentators love a narrative. They were patronising him the entire game and viewed everything he did through the prism of him picking up an injury before the game and not having much experience - they cheered him on like he was a kid who'd won a competition to be there, not a professional rugby player.
He's obviously an excellent runner and in both halves had some good moments, but the commentators praised those to the hilt while pointedly not mentioning his faults at all.
