I find meter making from backs extremely deceptive. It doesnt mean that much really. You could do nothing all game, take two length of the field intercepts and bang, you have run for almost 200 meters probably. I prefer to judge the forwards on meters ran, not backs.
Not sure where i can find his stats, but Moga at the moment has offered one try assist iirc, dont think he has made a line break has he? He has made decent meters, missed a lot of tackles and been pretty bang average in defence while offering little in attack. Pretty sure Reed, Kahu and Opacic would all have been better last season, and two of those pretty much played injured.
The good thing for me about Moga is he didnt quit, he didnt hide and showed a lot of mental toughness in that second half.
