Wortho is a twat. He does what he wants, plays like a thug, then whinges. On one play, he tried to hip & shoulder the ball carrier out of court, then whinged when he got called for the foul.
As I said above, Cairns were robbed, but I wouldn't focus on the Cotton call. The refs were calling soft shooting fouls like that all night. Besides Cairns played it wrong. They had the time-out, they had their instructions, and they did the one thing they shouldn't.
On the flop call, it was definitely a flop, but I don't understand why the rule is the way it is. Either there's a charge, a blocking foul, or immaterial contact. So either call the foul, or let play continue, and the flopper is disadvantaged by being on his back. If he's impeded the player with the ball, then call a blocking foul. Allowing the other team to put their best shooter on the stripe, then retain possession, is a big penalty.
