Did you hear the the press conference after the Storm game where Bennett said that he doesn't coach his players to slow the play the ball down. Other coaches do. If you notice the Broncos forward - Webke, Civ, Thorn etc - never dive on the ground looking for quick play the balls. Instead they struggle and strive for every metre.
I reckon, when it comes to the business end of the season, other teams begin getting desperate and try anything to win games, and do things such as slowing down the play the ball, diving in tackles. The Broncos don't, and that's why they struggle toward the 'business' end of the season.
Frankly, I take my hat off to them. On Saturday night, it was obvious that the Storm were slowing down the play the ball by getting off the tackle player one-at-a-time. If there were three in a tackle, the top guy would get off, then the second, then the bottom, when in fact, they could all get off together. On the other hand, the Broncos would all get off together.
And as we saw in the Orford no try incident, the officials are fairly easily fooled.
