For many years now you will notice teams especially in the first 10mins of each half slowing the play the ball for such an obvious extended time, not going back the ten or leaving too early--- wanting to give a penalty away. Why you might ask well some coaches have the theory it is better to rack up early penalty counts against themselves while fresh so they get away with more in the back end of halves when fatigue creeps in. Generating 4-5 penalties in the first 10-15mins usually means on average you will only receive a further 2-3 for the rest of the half and in some instances if you have a ref wanting to keep a low penalty count(for the whole game) you might only get 2-3 more for the rest of the game. The last thing a team needs is back to back penalties against them when fatigue is kicking in at the back end of halves---the theory does not always work out but there is a growing feeling it offers more positives than negatives. Too many square up patterns and rules that are not black and white allowing teams to dictate to refs not the other way around. Problem is it will take 2yrs of pain and constant outcry over way too many penalties given away to turn the tide---the coaches and players are ruling the game to the point of killing it.
