Struve - Not a contender anymore

Stefan Struve debuted in UFC with a 16-2 record and was seen as a legitimate contender in the Heavyweight division from day one.

In his debut fight, he was pitted against fellow contender, future Champion, Junior dos Santos at UFC 95.

Struve's first match didn't last long and didn't go well. He was knocked out inside a minute. However, the "Skyscraper" bounced back impressively with eight wins from his next 10 UFC bouts, which included victories over big names such as Paul Buentello and Stipe Miocic.

In perhaps his most impressive performances ever he won a Unanimous Decision over Brazilian legend, Antonio Rodrigo Nogueira, completely dominating his opponent with his long reach with stunningly effective combinations.

However, Struve ceased to be a serious Heavyweight contender when he dropped three consecutive fights to Alexander Volkov, long past his prime, Andrei Arlovski and Marcin Tybura.

Struve's best days are no longer in his future.
