It'll be interesting to see what he's like in a season or so.
No one should be able to break the tackles that he does or as often as he does, it really is a special, unteachable skill.
However, I also remember that Nathan Hughes used to bulldoze through tackles for us until defences adapted specifically to him, at which point it was necessary to start adapting his game.
I always have reservations about youngsters who have been able to dominate due to their physicality at age grade rugby because they often don't have the need to develop wide ranging skills.
As I say, is remarkable that he's maintained his ability to run through tackles at senior level, but the proof really will be in another season or so when he's no longer a surprise for the opposition.
