I think size played a big role in this fight. Alvarez looked like the much bigger, stronger fighter.
Dida's cool, I like him. But I dunno if he will ever be a top 5 LW. Too many holes in his game. He looks a tad small for 155, any chance he could make FW?
IDK If he could make it he also isn't in a gym with great weight cutters in Ninja and Shogun who both could probably be a weight class below where they are.
His last two losses where to two very big LW's in JZ and Alvarez which probably helped them dominant him on the ground but that doesn't mean he doesn't need a lot of work on his ground game.
