I've watched Wigan since the mid 1950's and Sam is the best fullback I've ever seen at the club.
As many have said those two tries against Saints were standout moments but for me my favourite moment and the time I realised what an exceptional talent he was came in an academy final v Leeds at Leeds.
In the semi v Widnes a mass brawl broke out and Wigan were then missing about five players for the final.
Wigan were just in front when Leeds kicked a ball just inside the dead ball line. Sam left it waiting for it to go dead, it didn't and Leeds scored. He was so annoyed with himself beating the pitch with his fists in frustration.
A few minutes later Sam got the ball about sixty metres out, beat three men with ridiculous ease and about thirty metres out slipped a beautiful pass to Chris Ashton who went in under the posts.
That's when I saw desire, competitiveness and will to win in him, something that can't really be coached.
