Brisbane Broncos coach Anthony Griffin says Curtis Sironen will change Wests Tigers' style Curtis Sironen in action for City. HE HAS just seven games to his name but Broncos coach Anthony Griffin is adamant son of a gun Curtis Sironen is dripping with talent and will change the way the Tigers play. There will be a 12-year gap between Sironen and his opposite number, veteran Scott Prince, when the Broncos clash with Wests Tigers at Campbelltown tonight. There is an even greater weight difference. Sironen, 21, weighs in at 103 kilograms, an extra 20 kilograms on Prince. Griffin praised the highly-rated Sironen who this week declared he wanted to permanently wrestle the No.6 jersey from injured superstar Benji Marshall. The Tigers have been written off due to Marshall's absence but Griffin said after watching the son of Balmain legend Paul for years, from under-20s through to NRL, he knew not to judge him on the number of NRL games he had played. He's a quality player. He brings a different dynamic to them at five-eighth," Griffin said. I watched a lot of him in the 20s. He's a big strong kid, a real runner of the football and direct runner like another forward. I'm sure they'll play a lot straighter with him there. He's not a ball player like Benji Marshall. He's certainly a handful in defence. The people they have there may not have started the year but they are elite kids.They will be direct and hard to beat. We are under no illusions how hard it will be to beat the Tigers at Campbelltown. Prince engaged in extra tackling practice at Red Hill yesterday, seemingly in preparation for the straight-running of Sironen, repeatedly smashing his shoulder into Broncos teammates. Sironen was solid in his representative debut for City vs Country in last week's widely derided event. He joins makeshift halfback Tim Moltzen in the club's untested halves. Sironen wants it to be a short stay. The Broncos confirmed Josh McGuire would tonight return from five weeks on the sidelines, but Griffin said his team were a long way off finding their peak. We are miles away. We have only played six games of football," Griffin said. Like I said when you (media) were all bagging the crap out of us, we don't listen too much. We're not interested in the feedback. If we start sitting on our hands now thinking everything is going alright the results will start to go against us.
