I could never understand why tall people are expected to be "bad passers". What does height have to do with an inability to pass? I just don't get it. If anything, it should be an advantage. The only thing that is negative is that big men are usually in finishing positions, so they aren't in a position to pass all that often. That's all. I can't think of anything else.
just overall coordination i think.. big people are usually just slower/more brute-like. less finesse/quickness. I mean just look at heavyweight boxing as an example. The difference between them and welterweights, in terms of quickness, hand speed, endurance, movement, energy is ridiculous.
but that's mostly at the high school/college level. in the nba, the vast majority of these big guys are uber coordinated.
