Come on, people claim Murray was better than he was. Yes he had half decent standup, lots of power and was tough as nails, but Anderson Silva took him down with ease. If Silva can do that with his non existent wrestling, the entire UFC MW division would be able to as well.
Bisping would have taken Murray down repeatedly. Bisping's takedowns aren't recognised much but he sets them up well. Against anyone who isn't a good wrestler/grappler he easily gets takedowns. He's going to do it to Rivera and he would have done it to Murray too.
Murray was no way near as good as some people think.
