He is only 21.Agree. Batting at 6 seems to fit his style/experience, his technique seems compact and he seems calm. It's a small sample size, but you can see why some in the England setup are excited to get him into the team. Plus he's scored runs in county cricket too.
A lot of the commentators yesterday were suggesting that he should stay at 5 or 6 for a while but could end up at 3 in a few years time (Ian Bell worked his way up the order)
He looks very composed and Alec Stewart clearly rates him very highly.
