Yeah, I don't think there is anything wrong with Cater Gordon, it's just a decision from the team to not play him. It looks like they (or management) are determined to shoehorn To'omua into playing 10. Also makes it insane that they loured Cater Gordon away from the Reds. Surely, after signing him they have to be planning on getting him SOME game time, honestly the Rebels not playing him after poaching him from the Reds would be classic Rebels.
I wouldn't go so far as saying To'omua is/would be the best 12 in the World, but he's a really good 12 and only really a serviceable flyhalf. Personally if I were coaching the Rebs I'd probably be playing Gordon at 10 and To'omua at 12. And Hodge at 15. It looks similar to last year when they played Deegan at 10, they just looked so much better with a REAL 10. It feels like maybe management or To'omua are insisting on him playing 10 because even last year after Deegan had their attack humming they went back to To'omua very quickly.
But I'd love Hodge to get the rest of Super Rugby at 15, he could be an awesome fullback, and he's got all the skills you'd want from a 15. Massive boot to win those kicking duels, good enough play-making to be useful from fullback, a big strong ball runner, and really good under the high ball. Honestly, he'd probably be the best fullback option we have right now (mostly because Campbell is a bit average, and Banks & Maddocks have been poor).
