He may be a nice lad, but if he didn't really cut it at Wigan and he's not really cutting it at Sale, what does that say about him as a player at the highest level - in either code?'"
As someone has said above the club did what they could to keep hold of him so your theory that he did not cut it Wigan is your own theory not what actually happened.
IIRC Thornley opted to go to college and study rather than train with Wigan full time. He left the club at 18/19 years old, very rarely do we see players of such a young age playing first team.
