I don't think that is Gastelum's weight class. He's caught in a tricky situation, too small for this weight class, too big for the lower one. Looked like his game plan was simply to land the knockout punch, at this level you need more than that. He got close in 1st round, but you need more weapons against top level fighters. Weidman looked ok, he seemed very emotional at the end, maybe finally getting a win, and fighting in front of his hometown got to him. He and his corner responded very well to the knockdown, neither panicked. Be interesting who he fights next.
