I don't think its an easy transition going either way. Andrei is a tremendous athlete with good pop and hand speed but I don't think he really can compete at this point with most top 25 boxers. It really baffles me that people think that b/c someone is a top player in their respective combat sport that they can just seemlessly transition to another. On another note Andrei didn't get dropped by UFC b/c he lost he got dropped b/c of the passivity of the way he won his last fights. Dana is a dirtbag but if you watch Andrei in his last fights it wasn't the same guy much less entertaining.
