Um, Robert T's being 9 years old, and 9 fights-tired, had more to do with his losing than Ch Ninja's being the better dog. That and the fact Robert T broke his jaw in the first :10 ... old age = brittle bones ... and yet he still went 1:10 before he lost.
That is like singing the praises of Leon Spinks for beating an old, shopworn Muhammad Ali ... rather than having the sense to realize that Leon Spinks was A PIECE OF SHIT compared to a prime Ali
