Similar in many ways to when Leicester City won the Premier League.
Not too many famous names but a great team spirit and a fantastic work ethic.
Backing up the man with the ball involves a lot of effort and quite often a lot of disappointment but when something comes of it, it makes it all worthwhile. Castleford have been great at it all season and it has been instilled into them by good coaching and good player attitude.
I wonder how good Wigan's backing up might be if they were being coached by the greatest 'backer up' of the past 30 years - Shaun Edwards?
