Wouldn't surprise me. The article says the coaches weren't listening to their scouts. You could write a thick book on the number of times that's happened in the past decade alone. "Nigerian bias" would be about #273 on the list of reasons why owners and coaches make the decisions they make.
Bottom line, to me, is that many NFL decision-makers don't truly know talent. They get distracted by hype and The Big Board and make stupid decisions. Blaine Gabbert at #10 is another bad decision, as is Christian Ponder at #12. There are about a million "biases" in the NFL.
That's why, when you get a franchise that really knows what it's doing, they tend to be successful for long periods, not here and there. The Patsies, the Steelers, the Packers, etc. Contrast them with the Browns, the Lions, the SeaChickens. Some folks get it, some don't. Some who don't own teams.
