Three years of inactivity in the 30s for anyone competing at the elite level of any sport can have a huge impact on performance. Now, in terms of "no excuses," no one else made Jones not fight during that time, but you can't state that Jones hasn't slipped from his peak until we see what he looks like. He could win and look like shit, he could lose and look great, but he can also lose and look like crap, and not because of Gane. It's kind of silly to pretend that age, inactivity, and, certainly, both combined have no impact on elite athletes.
