Any white player on defense, other than linemen, will be attacked as being slow and unathletic. Happened all the time last year with Kiser / Bertrand. It was the same with Tranquill. I was here during the Harrison Smith days and it was no different then.
Those that engage in this are too stupid to provide meaningful insights, so they just revert to the predictable, Pavlovian, knee-jerk commentary because it requires the fewest brain cells.
