Didn't Lacy tear his rotator cuff against Tsypko? I don't think you should him by that performance even if the decision was questionable.
Yes, this is why we have no idea what to expect from Lacy. The last time he fought while fit and well was in March 2006. And he got spanked from pillar to post. This is a massive fight for Lacy. He needs to make an impression on Saturday. There's lots of pressure on his shoulder(s).
