Here is the deal. Two evenly skilled players, one is 5'11 and one is 7 ft. Who should win that rebound battle when they are matchup up against each other? The 7 footer. Rondo is a good rebounding guard, but he gets most of his rebounds away from the rim. Imagine him trying to guard a 7 footer? He'd get smoked. Of course one factor we cant see is where the rebounds are going.
but the smaller guy have trained a lot more to reach the level, right?
When height matters, they should make the training the same ... And when they do it, players height should be influenced the salary.
And must important you can not compare players anymore, maybe you are looking today for a prominent rebounder so you go on the transferlist and put rebounding prominent in the mask et voila you found 50 guys you like to have. With height matters, you look for strong rebounding from a 7"3 guy, or profient rebounding from 7"1, or tremendous rebounding from 5"11.
Would this make the world a better place? i would say clearly no.
After the first big guy training height matters, and when it comes to making the players it also matters because small guys get more likely good guard skills, and big guys big man skills it gives some small guys who could compete in low level with big guys in the frontcourt(and the opposite way), but as higher the competition get the less player like this exist.
And i am not a small guy, and i am not very talented on court they are smaller guys who could out rebound me who didn't play a lot, and they are even some bigger guys who have a bad motorious ability whio i out rebound ;) And on free court i see that often that smaller guys dominate in the near of the basket and you are talking about this level of competition.
