It has become virtually against the law for great white athletes to play running back, wide receiver, outside linebacker, cornerback and safety at the big-time college football programs. Thus, you see that the pathetic NFL has virtually no white players at that position. Big-time college basketball is a little more fair to the great white athlete, and the NBA to a very slight degree, but not much. Many of the great, white high school athletes face the reality that big-time college football and basketball is not going to give them a fair chance, and now choose to try baseball, soccer, etc. .. Say you are a great white wide receiver in high school, run the 40 in 4.45, have great hands, are 6-2, 190 pounds. Your best chance to play big-time college football might be to try to gain 40 pounds and take a try at tight end or middle linebacker.
Or switch to golf.
These are your NFL White Running Backs:
Rex Burkhead of the Houston Texans
Christian McCaffery of the San Francisco 49ers
Ryan Nall of the Chicago Bears.
Most of the better white b-ball players are now from Europe, e.g. Luka Doncic.
