that reasoning is valid only because BB is not considering height in that equation.
That is not the case... for example, (let's use the rebounding skill in this example) the NBA now is composed of tall, quick players, and in 1991-1992 season, Dennis Rodman (Height:6'8) leads the league in rebounds (averaged 18 rebounds per game) infested with players who are bigger than him (Robinson, Ewing, Olajuwon, Mourning, and Mutombo to name a few)
Now, why is this possible, maybe because that Rodman may have a better rebounding skill level than the others, and thus, makes him legit to be better in spite with his height.
Another example, a 6 footer player who seldom plays basketball can be out-rebounded by a five-footer player who is a veteran at the game... most especially if he is skilled at boxing out a player.
It is usual that big men rebounds well other than smaller players. But with better training, and if the smaller player out-trains the bigger player, he has a good chance in the ball, because for me, it's all about the skills, not the height.
And also, I don't see any 5 footer players here in BB who are good in rebounding and out-rebounds bigger players, and even though there is one, the credit is in the manager who trains him, not the player itself :)
