There's a lot of places I could start this: the smashing he took, the gassing, the criticisms from Dana White, and I'll touch on all of those, but I'm going to start with the game plan that Jason Miller had for his fight against Michael Bisping. In the leadup from The Ultimate Fighter: Season 14 and in the pre-fight pressers leading up to the event, Mayhem mentioned the knockout from Dan Henderson multiple times. Let's look at that and remember the good times for a bit.

It's glorious. Let that marinate for a second or five. Now perhaps I'm reading too much into this, but I think that the fight backs up my assertions here. Miller was trying to H-Bomb Bisping because he felt that one of his best avenues to victory was landing the huge blow. On a strange tangent, Georges St. Pierre tried to do the same thing to Jake Shields, again trying to take a page from Hendo's playbook. Anyway, this lead to Mayhem throwing wild haymakers in an effort to try and put away Bisping early. This also lead to his gassing. Throwing everything you have into huge arcing overhands is a drain, and something that Miller, to my knowledge anyway, has never done in a fight before. This is also a gameplan he's never utilized before (at least that I'm aware of, blast me in the comments if I'm wrong and you know better than I do).
Remember, he grappled with Jake Shields for five rounds and was five seconds away from winning that fight.
In fact, while Miller's striking is not his strongest asset, it's generally been good effective volume punching and kicking - much the same way that Bisping usually fights, and to some extent, Nick Diaz. He got away from that early in an apparent effort to get a highlight real KO when the fight was on the feet.
