Doh! I forgot the Lineout work! Though that's perhaps not so specialised.I see the mordern second row as more for muscle in th breakdown as opposed to jackaling for the ball, engine in the scrum is pretty essential but can be less essential if there is excellent lineout skill. You do look for yards gained as well but this can be either through pace or power. Not so easy to define a second row now as there are some that a more a converted 6 and specialise in different skills to some out and out second row enforcers.
From my poing of view, Itoje has not played what I would call badly but he is also not the stand out he was a few years ago. The constant change of position under Jones would not have helped and hopefully training under SB will bring back up to elite level in a pretty short period of time.
