I think people need to slightly move on from the theory that props and hookers in the early to mid 20s are still babies in front row terms. The days when a prop wouldn't get into the first team until he was 25 and kept getting better until his late 30s as he master the dark arts have gone. Ovviously players will keep developing throughout their career and hopefully keep improving, but 23 is no longer young for a rugby player, whether in front row terms or not.
I am pleased with his re-signing, but his throwing, after a strong start, did suffer. If Ward is going to be criticised for it, and rightly so, then so should Elia. If he improves though, then happy days. No guarantee though - look at Youngs
