I've always admitted that Kvesic has a higher ceiling than haskell but I don't think for one moment that the way to make the player realise that ceiling is to throw them in at the international level before they show their best form - this is why I disagreed with Burns being first choice 10 over in New-Zealand as a way of 'forcing' him into some semblance of form, and it's exactly why I don't think Kvesic should be our first choice 7 here and now.
You've made the point that hes getting through a large amount of work - tackles for example - but frankly, the reason we have high expectations of him is not because he could make 30 tackles, it's for the other stuff which traditional 7's do which, either through Gloucesters fault or his own, we're not seeing all that much of. If it's a tackling openside we want, why look to Kvesic when we have the likes of Robshaw who can also carry, be a link-man between backs and forwards, and lead the team effectively. If this is the basis for which you'd pick an openside, why look beyond Haskell who is tackling most opposition back behind the gain-line, jackling ball, and carrying well ( I don't believe that stat about Haskells metres made to be honest)
It just doesn't add up - and as I've said, you can't, CAN'T pick someone at openside on the basis of potential alone.
