Predominantly....
Mainly, mostly. Indicating the most noticeable, influentual or numerous feature.
So he hasnt predominantly played prop has he? He has occasionally, and that was due to the old "make sure your best player gets the ball often" coaching. They couldn't leave him on one edge and risk him not getting the pill.
You made a mistake saying he has predominantly played prop, I have no idea why thats so hard for you to admit. I have already acknowledged he was poor last week, and I think he has guys really nipping at his heels for his depth spot. This is his last year on contract yes?
