I think there has been some success from ex-Patriot coaches. Eric Mangini, for example, and to an extent Flores in Miami seems to be doing a decent job so far.
We all know Mangini was black-balled for the spygate incident as well as employing Hillis as a lead back and ending the white running back 1,000 yard drought.
Interestingly, Hillis was, no my knowledge only the 3rd white running back to be considered a featured back since Craig James in 1985 (Hodge for about a year or two and Alstott also got a lot of carries in Tampa early in his career). What this essentially proves is that if a white many is given an opportunity he comes through with flying colors.
Hard to argue with sound logic and factual evidence but the cucks that make up the majority of men nowadays find a way.
