In McDaniels' first draft as head coach of the Broncos (2009), he drafted 3 whites out of 10. He had a white QB (Orton), started 4 white OL, and allowed Brandon Stokley and Tony Scheffler to start at WR and TE. Every single defensive starter, and backup, was black. Of course, future superstar RB, Peyton Hillis, was on the roster and only received 13 rushing attempts...a total screw-job that made all CF posters livid...
CAPTION: What Might Have Been
In McDaniels' second year with Denver (2010), he drafted 5 whites out of 9 (Tebow, Decker, and 3 OL), the most in the NFL that year. Hillis was traded and became a star in Cleveland. Stokley and Scheffler were replaced with blacks. Decker returned punts and kickoffs, but only managed 6 catches. McDaniels was fired before the end of the season.
I'm not sure what to think about Josh McDaniels. The Patriots are so secretive that it's difficult to tell who's responsible for their 10+ years of fairness to white pass-catchers. I once though that former Patriots QB coach and OC, Bill O'Brien would be fair to white WR's, but he wasn't fair to them at PSU and hasn't had a single one as the HC of the Texans. During O'Brien's time in NE, the OL was almost exclusively 5/5 white, with usually only one black backup on the entire roster. Thus far, his OL in Houston is routinely 4/5 non-white.
The only coach in the "Belichick coaching tree" that was overwhelming fair to white players as a HC was Eric Mangini, who last coached in NE back in 2005...which was 2 years before Wes Welker was signed in 2007, essentially beginning the franchise's decade-long fairness to white WR's.
