According to this article by NFL.com's Pat Kirwan...the NFL's Best three O-Lineman are Nick Mangold, Joe Thomas and Ryan Kahlil..when adding Group "A" Jake Long & Jordan Gross...5 of the Top 6 are white...and the complete list of 25 has 16 white +4 of 6 on watch list for Future = 20 out of 31..not bad considering the NFL is 67-70% black?? This is good to see that things are still going strong at this position; not to mention many of the players mentioned are young and just entering their primes...
