Cheers to Moggi for all he's done for the club. But despite the fact that I think his side of the calciopoli story is seeming more and more credible with time, Juve does have to take the high road here and sever ties with an ugly past. That Juve "cleaned house" was a bold and positive step that no other club involved with the scandal even came close to attempting, and to bring back old names would only mean all was for naught.
Juve has to look forward, not backwards. I'd love to have Moggi somehow help the club in a different capacity in the future. But for now, I think that could best be served by avoiding public (and private) contact with the current Juve management while sticking it hard and heavy to Telecom Italia and the Inter management.
