Yes but we have eyes and logic.You mention inconsistency as if weight is supposed to remain consistent. The Nate fights were his first time outside of 145 in the UFC. He's had time to get bigger since then. The chances of him just gaining 6 pounds after weigh-ins are zero.
A couple of years ago when he was fighting at 145 we were lead to believe he was easily 170+. And then we can visually see he bulked up after he left 145, by his own admission he ate like a pig, and he looked bigger than we'd ever seen him against Nate, and yet he only weighed in at 168. So either he's not as heavy as we thought he was, or he actually did cut weight for the Nate fights and he's lied to create the David vs Goliath narrative.
Again you can see the difference between Alvarez and Nate fights, he came in lighter with his abs more visible.
Lockhart has said in 3 seperate interviews recently that he expects Conor to barely cut any weight for this and be 160 absolute max. So one of Lockhart and Conor is blatantly lying, they've contradicted each other.
