It's what, 3 games though? Barnes has reffed Ireland about nearly 20 times, and we average 2 more penalties with him, I doubt very much that he's biased but applying your argument to that trend and including the Stephen Ferris call in 2012, the entire Wales game in 2015 and his first half calls.against France in the Autumn and he's biased all of a sudden. In reality, he's cost Ireland at most 2 games, and apart from the we've just not been good enough when he refs.
Gauzere clearly doesn't control the clock well and it's very unlucky for England that it cost them twice but he also gave nearly half of those players today one of the easiest rides they'll ever have in a rugby match 6 months ago. I don't think anyone is wrong that there should be actions taken against him but having a go at his integrity is too far, he's just way out of his depth.
