Lee's challenge was accidental but also the culmination of every Saints player looking to belt anyone who took the ball in after Cooper smashed Bentley. They took it personal and made it their mission to deck the Warrington team. The offload to Roberts came from a smash hit and then they were all looking for Roberts who bumped off one defender, and got grabbed by another round the legs. Lee's was looking to smash Roberts just like the rest of the team but this time he fell and Lee's caught him awkwardly.
Unfortunate but the card was needed to diffuse things. If that had gone unpunished then it would have carried on throughout the match decending into team brawls every 10 minutes instead of the one that happened. There is a lot that needs looking at in the game as is.
Patton late on Richardson.
Cooper's hit was dubious.
The brawl had some furious punches thrown.
