c00n thread.
Even without the race mixing, African-Americans are made up of several different West/Central African tribes. To give you a personal example, I'm half Malawian/Zimbabwean and as a result I don't quite fit into the stereotypical look of either. Zimbabweans are shorter and much slighter in build than Malawians/Zambians who tend to be much taller and heavier framed and somewhat lighter complexioned. My facial features don't really fit comfortably into either stereotype (although body-wise I'm much closer to Malawian). Now imagine what all the inter-(West) African breeding bodes for African-Americans who are a hodge-podge of a shytload of tribes/ethnicities from Kirdi to Igbo to Kru. Of course you'll look a bit different.
That being said, I seriously doubt you'd be able to tell Serge Ibaka, Nnamdi Asomugha, Wale, Masai Ujiri and Oguchi Onyewu are specifically African and not African-American without prior knowledge. You're stereotyping the shyt out of Africans and honestly you sound like a cac the way you lump us all together so dismissively. There's NO "African look" whatsoever. NONE.
