I have absolutely no problem with Williams fighting at 160. Afterall he is taller than almost any middleweight. In fact he is taller than most supermiddles!! I think he would be a better middle, because so far he has been torturing himself to make 147. The problem I have with this fight is that his first fight at 160 should NOT be Pavlik. That is bad - both for Williams and for Pavlik - because Pavlik will get no recognition. Let Williams meet some noname and then Duddy or Mora next. Thereafter we can make Pavlik. Sizewise Williams is a big middleweight, but he should not meet Pavlik or Abraham in his first fight.
Btw. the greatest away fighter of all time most be Monzon. He basically had his entire career on the road.
