They could still ask her (Tanith) though. But then again, skaters she coaches are reserves for the Olympics and there could be an issue if a team does withdraw.
But Agosto would be a good choice.
Jean-Luc has a close personal relationship with one of the contestants. It's hard (impossible?) to find a commentator who doesn't have ties to some of the participating skaters. But seeming bias towards some skaters is better than a strong bias against.In replacing her, I like Ben, but I'm pretty sure he's busy with his ice dance school out in CO. I think Jean-Luc would be a good choice.
WRT Gabby, I think her comments about Cizeron may have disqualified her even if he hadn't denied them/stuck back.
