He's alright, has a lot of potential (imo) but is pretty untested/raw

He isn't getting regular game time at Ospreys (I think he has more Wales caps than Ospreys ones? that's what Wikipedia is saying, but I don't know how recently it was updated) so gets most of his rugby in the Welsh Prem. - though he has played 7s for Wales as well

It's like taking an 18yr old from Bedford Blues and chucking them into the England squad.
