I agree as a player that his strengths appear best suited to 6 or 8.
I’m just saying that the best season he has played at the Reds, IMO, was 2 yrs ago. And, from memory, he played predominantly as a lock. I don’t remember it nullifying his game at all.
Which doesn't mean that lock is his best spot - maybe he would have been even better at 6 - but it does say to me that he is effective there at Super level.
