I didn't hear or see it, so I'm not commenting on the actual performances. But Teddy Tahu Rhodes is actually quite a coup to be able to snag for a last-minute replacement: he has a substantial career going, and I remember him being a strong Ned Keene in the Peter Grimes simulcast. No doubt the attention he gets is partly due to his looks and physique, but I think there's a real vocal and musical-dramatic gift there.
Now, it may well be that he didn't do himself justice in this performance, or that the role isn't suited to his voice (it's oddly unsuited to almost any bass or baritone who isn't Josť van Dam). I can't speak to that, I wasn't there.
