Wesser, while not setting the world on fire is earning himself a superannuation gig in the UK.
I've been as critical of him as anyone but he is doing as much as we could have expected from him. When we signed (and then resigned) him we knew we weren't getting a worldbeater at this point of his career, we were getting an expierienced veteran who could:
a) hold the fort until young talent came through at the fullback position (and it certainly has in Roberts)
b) perhaps pass on some expierience to that young talent.
He's done that and good on him. If it wasn't for Wesser we likely would have had to throw in Roberts too early at fb. This way we've been able blood him on the wing and when he is given the #1 jersey in 2012 he'll have 10-15 games expierience in a relatively low pressure position which will make him a better fullback.
Roberts is the real deal, has speed to burn which is the one thing you can't teach, looks like he belongs at NRL level, hasn't been overwhelmed yet (keeping in mind he's still just a teen). He should be one quarter of our spine for a long time to come.
