He left to be first choice somewhere which he wasn't at Wasps.
I don't begrudge him that at all.
Unfortunately, that won't change if he came back and he'd likely struggle to make the bench.
Willis, Young, Carr, Shields are presumably the first 4 choices.
Then we also have Vailanu, Johnson, Tom Willis.
I feel that Guy would be fighting it out with this group.
I wouldn't be upset to see him return, but I feel that he'd be looking for somewhere that will give him a good chance of playing regularly
