Ardie and Beauden are interesting in that there is a real disconnect between the general public and those that really watch rugby. I don't think I've really seen that before to this extent. Both are freakish athletes who can pull off insane acts on the field, so their highlight reels are amazing, but they hard to pin down as rugby players as they don't really naturally fit into any position.
Ardie is way better suited to 8 as it gives him more freedom to roam, which is why previous AB coaches preferred him there, especially if you pair him with someone like Cane or Dalton at 7 to do the grunt work. Moving him to 7 this season is just another absurd decision in a long list of absurd decisions from these coaches. He would also likely be a real weapon off the bench.
I actually think Beauden is best suited to the 23 jumper at this stage of his career, and that's where some of his most influential performances have come from. Though he has dominated games from 10 in his heyday, it wasn't through traditional 10 play, it was through pulling off freakish acts scoring and/or setting up a bucket of tries. If not on the bench, then he's much better at 15 where he has more space and his weaknesses are not nearly as apparent.
Playing Ardie at 7 and Beauden at 10 all season were probably the two most critical selection errors the coaches made. It meant that we had an unbalanced loose trio, so we mostly lost the battle of the breakdown, putting us on the back foot. Then we paired that with a 10 that has relied on his pace in the past, so doesn't do well with limited space on the back foot. An obvious recipe for disaster that were persisted with all year.
