I can't remember the direct quote, although my quote was off a bit. It was something like:
"You're going to jab a few times, go for the double, and put everyone to sleep"
Something like that. Can't remember if he said "get the double", or "go for the double", but the "put everyone to sleep" part, is essentially conceding that it's going to happen, and he definitely said that.
I'm obviously reading too much into it for fun, but I do believe Bisping is consciously trying to soften the blow of his inevitable unanimous decision defeat. He's desperately trying to goad GSP into not using his wrestling, and already discrediting the style as trying to "avoid a real fight", or not fighting "like a man". It's like he's already lost that way to GSP, and trying to hype up a rematch or something.
