Pretty much. AWJ has been a class act since the first time he stepped onto the field for Wales (out in Argentina I believe), so that discounts anyone claiming his only good quality is experience. He's a workaholic, he'll dominate 90% of the tackles he puts in, he makes some hard yards when required, his hands are very good, capable of making offloads, securing a lineout one-handed, linking play. His standards do not drop for the entire 80min.
If you want a highlight reel player, Jones probably doesn't fit the bill; but a rugby team can't be made up of 15 highlight reel players, they'd be blown off the park as there'd be no 'glue' to hold the team together. Jones is that 'glue' imo. His only like-for-like rival in the second row is Kruis imo. One of them will start out in NZ alongside the athletic Itoje (so long as he fully rediscovers his form), and given Jones' superior experience, his leadership and captaincy credentialls, and the fact that Kruis has been injured, Jones is in the box seat.
AWJ looked a little tired in NZ in the summer. He'd played a hell of a lot of rugby, with very few breaks (partly because he's very rarely injured), and it seemed to catch up with him. But he has responded well this season to the challenges of Kruis, Itoje etc, and for the Ospreys at least, he's been playing the best rugby of his career. He's added a dynamic carrying game in the wider channels, one handed offloads etc. to his otherwise excellent all round game. There's more to come from him this 6 nations.
