ok give me 10 Euroleague players who can play with Scola or Marcus Goree. Then give me a player who is 195cm that can guard them It has nothing to do with what league you are in. I am in the top league in Israel and my players are not poor and I'm sure my competitions is not as well which means that some sense of reality should be put unto the game when i give the ball to my center who has 15 cm on his defender and he cant get a shot off is not realistic.. It does not have anything to do with what league they are in. It is basic that height and speed can help some players out.
There is no 195cm player who can guard a 210 player with even skills at any level in the world.
Of course it has everything to do with which league you're in. Sadly, some leagues are just better than other leagues, and it is not surprising that you find the best players in the best leagues.
Ironically, Luis Scola is 6'8, and he's doing pretty well against guys much bigger than him. Likewise, I've seen 6'8 Leon Powe and 6'9 Glen Davis match up pretty well with 7'3 Zydrunas Ilgauskas and 7'2 Shaquille O'Neal. OTOH, giants like 7'2 Bruno Sundov and 7'0 Nikoloz Tskitishvili were unable to stay on an NBA court for meaningful minutes, let alone have some impact.
Because the game is pretty young, people probably still consider proficient and prominent good skills for top centers. Do note, however, that these are just 2 levels above the best skill that can be produced in a drafted player.
I will go out on a limb and claim that when the player supply shakes out, top centers should have sensational or better inside skills. Good luck training a 6'6 guy to this level.
I will give you a short example: if you rotate training, a 6'9, 18 year old guy averages a level less on all inside skills than a 7'4. 18-year old guy. So a 6'6 guy probably trains at half speed as compared to a 7'4 guy. You do the math.
