Most of these guys are fringe contenders, B level fighters at best. I have been digging knee deep in the Heavyweight division, there isn't much there that's going to rise to the top. Even Granat lost a couple of rounds against Franz Rill and didn't look all that good until the knockout (which was legit, dude was out). Teper/Hammer was a pretty close fight, I think that Christian Hammer was just more accurate and slipped more punches. That fight didn't go as I imagined it would.
Teper showed in previous fight he had trouble if he didn't knock out his opponent in a couple of rounds. Duhaupas lost to Teper, but in my view it should be a draw or even a win voor the Reptile. Teper doesn't have the tank to go the full distance. This fight showed it, Hammer is durable and cruised to a vicory.
A fight with Hammer would be interesting... I consider Hammer to be superior to Charr who gave Duhaupaus some issues. Duhaupaus would be the rightful favorite, but Hammer would certainly be a live underdog.
