For me, it would have to be Eddie Alvarez's. It was very satisfying to have watched Cerrone outclass him. After Donald had a series of highlight performances, seeing him be the underdog here and comments making him out to be a scrub coming in abundance (like "Eddie is going to make Donald look like he belongs in Bellator"), it was just a feel-good moment to see Cerrone's consistency come through. Additionally but to a lesser extent, watching Mendes and Melendez stopped was merry 'n dandy. Edit: Okay I was overreaching in attributing hype-trains to these two. Shh. You folks? Edit 2: Since lots of people seem to think it's unfair to call Eddie Alvarez a hype-train derailment, I explained why here: http://forums.sherdog.com/forums/101831393-post109.html Spoiler Here is my thinking behind attributing the term to Alvarez: A hype-train would have a large backing of people who attach clear and high expectations, and there would be a consistent inflation of the fighter throughout his perceived future success based on earlier success. A shortfall in merit. Read this thread if you will: http://forums.sherdog.com/forums/f2...d-cerrone-ufc-178-update-bobby-green-2807667/ 34 pages and plenty of room to make my point. The UFC has a deep, deep LW division - it's arguably the toughest division. A fucking shark tank. Can we all agree on that much? I measure his success in another organization and weigh it against people's expectations of him in this one and see inflation. Really, go through that thread (and there are plenty other dispersed posts throughout the forum that I'm not going to be bothered finding). I'm comfortable in marking it a hype-train especially when those expectations came off a kneejerk reaction. None of his earlier success warrants a solid expectation of being royalty in the UFC's LW division and that's how he was made out to be (and I'm not being selective in representation).
