Nobody in the comments is willing to say the VERY obvious. The fans wanted hip swivel, burst, and twitch; not blue collar, lunch pail (or pale), and non-stop motor.
.....and whether these descriptions are true or not of any player be they black or white, there's more than one way to get the job done. Why is it a bad thing to be blue collar, lunch pail, non-stop, heady, etc.?
I've seen it many times in football especially high school and college where a team is hyped for being explosive, fast, etc. and another team is described as blue collar and the blue collar team destroys all that speed and twitchiness, especially on the defensive side. I know we've all seen it, but I took in a HS football game last year where this explosive black offense was going to destroy this blue collar all white team. Well, guess what, the blue collar white team held this explosive offense to "0" points until the last few minutes of the game when the second string defense was in. The final score was whitey and blue collar 35- black and twitchy 7!
The defense destroyed that high powered offense because they knew how to play football. Whitey's offense ran the ball right down their defenses throat! Blocking and tackling, something that's rarely seen anymore, especially tackling. No wonder these offenses score so much in college and NFL. The mostly black defenses lack the ability to tackle!
Football is about blocking and tackling and HS, college, and the NFL has gotten away from fundamentals just as the NBA has.
Give me the smartest and fundamentally sound players on either side of the ball and I'll beat twitchy and ignorant all day and night!
