It depends who else is in the squad, he would certainly have not played prop for Warrington when he was there, they had him on the wing, which he actually did quite well for them.
Fax played him second row sometimes, as we have, but because he's got abit of pace he's suited to both. He is the size and frame of a modern day prop though, so I can see why Betts has turned up and put him there. Doing very well at the moment.
