Thank you, someone else spotted it - yes the rules state 'the attacking team CAN have a water carrier on the pitch' and also a physio for an injured player but whenever your opponents have the ball this happened (practically every game I've seen on when you're on tv) ....
The 'trainer' in a yellow top was stood with his back to the pitch looking up to Nathan Brown in the stands and talking on a radio - he then turns to the 'water carrier' in orange an repeats Browns instructions. As soon as he can, onto the pitch the guy in orange would run, to 'offer' a drinks bottle but all the time talking to the player - he goes from player to player and occasionally cames very close to having the ball passed to him! He even waited mid-pitch to talk to a specific player who was involved in the play in progress.
No this isn't a whinge about you beating Rovers, yet again, we were outplayed by a team who were given the opportunity to get close to the try line by accepting silly conceded penalties (no excuses from me) - when Rovers got one we were 90 metres from their line!
Lets see what the RFL & Boots 'n all say on the matter shall we
