I would say Dak Prescott and Russell Wilson are the two best black QBs since Warren Moon, which was a long long long time ago. Wilson has gone downhill quickly the past two seasons and now seems washed up or close to it. Prescott is now a pocket QB and has ups and downs but is overall still solid. But he's only 30 years old, which is semi-ancient for a black quarterback but young for a White one. We'll see if either or any of the onslaught of black quarterbacks in recent years have the stamina and endurance that all great White quarterbacks have.
