I don't agree with the call for a penalty try and a sin-bin though. If a penalty try is given then the offender hasn't prevented a try, so they shouldn't be sin binned, as that is what you need for a sin-bin in the first place.
While 2 wrongs don't make a right, having an extra man for 10 minutes should have meant that the Tigers did much better in this match, so I don't think the call cost them the match. They either should have been more ahead than 2-0 in that 10 minute period, or they should have come home stronger at the end of the match due to fatigue of the Storm players. It's hard to say what is the bigger advantage/disadvantage, a penalty try or 10 minutes in the sin-bin. I would probably argue it's the sin bin (given what happened in origin a couple of years ago, and also when Gillett was sin-binned against the Dragons a couple of yers back when he was 40 metres onside). Perhaps had the Tigers scored 2-3 converted tries in that 10 minute period, you could say that the Storm were unfairly penalised.
