I don't think he would have sent the CB to open table if he was trying anything safe at all.I doubt he was playing the combination . Perhaps the 4 into the 8 to leave the 4 behind those balls? Think he over hit the shot because he was trying to draw whitey back and back across.
I think he was playing the combo and we have to remember he plays far better than we do. if he sees the line the ob ball needs to travel, he can send it thatta way. Don't bet otherwise!
Another option is the cardone theory that sometimes the likelihood of positive outcome is so low, you don't fight this rack and save the fight for the next one...maybe mickey closed one eye and hit it with high fukitol spin.
