Yes, of course. Marotta has a following and people like him, because he has been fabulously successful so far and his strong Juventus past is well known.
Back to reality, you judge people on their methods. I thought some of Secco's methods were well meaning and positive, although he was ultimately clueless. Does that make a person a Secco defender? I've seen many of these potential 'Secco defenders' in this forum during Marotta's spell, talking up the big money moves we made. But of course they are not Secco defenders, they are just giving their opinion on his methods, just as there are no Marotta defenders on this forum. They are either seeing a different side to the method or they are overly optimistic.
I prefer to judge events in isolation, rather than complain about every single detail because I didn't like several events in the past.
As for the Ziegler situation I don't have any problem with him leaving if Conte feels he cannot use him. From a personal perspective I wasn't enamoured with his signing anyway, I don't feel he is particularly better than De Ceglie. My concern is the fitness of De Ceglie and where that leaves us if he is missing. So I agree with those who wonder why we didn't sign a replacement if he was going. If this is Conte's choice then he will live and die by his decisions, like every coach. The same goes for Marotta.
