Ali and Taylor were hard to beat if you boxed like girl with them but that got boring after 5 fights. Oscar at the heavier weight lost to much stamina. Leonard could be used effectivley to beat Oscar.

At feather Morales V Chico was usually a long bloody and cracking fight. If you used Morales you had to box smart only get involved when you could get in and out. With chico the trick was to force Morales to fight and you would normally come out on top. Taylor V Hagler was much the same theory.
