You just said it. He has fought defensively with a strategy to keep a belt. He brings no killer instinct into his fights. He's shitty, not a good fighter at all. He got lucky in Arlovski fight 2 and neither him or Andre wanted to win number 3. Jeff Munson didn't stand a chance and it was Sylvia's chance to showcase his fighting abilities. Instead, it was like a sparring match with a big couch that didn't involve any good action. Couture, like in all of his fights will bring the action. Age will also not be a issue in this fight just because Couture is in better shape than Sylvia. Everybody thinks he stopped training but that's his career. He stills trains with his younger developing fighters and camp. Word.
I'll give Couture a chance but I'm sure his comments about Sylvia fighting without heart will bring out more of Sylvia's old offensive style. The way I see it in my head says that Sylvia has a 70% chance of winning this fight to Couture's 30%. I personally think it was smart (not cowardly) of Sylvia to fight defensively against Arlovski because Andre is a great striker. But back to Couture, Sylvia has the reach advantage and can still hit hard if he needs to.
I'd also like to add that your band is awesome and I really like the album.
