Brad Fittler admits he can't ensure his record 11 NSW State of Origin rookies don't crack under pressure at the MCG against Queensland on Wednesday night.
The Blues have just one training session left before the series opener, where they will run out as the least experienced side in more than three decades in the Origin arena.
"I can't ensure that (they don't crack) at all. But so far, so good. It's been a good camp," Fittler said.
