It is important to remember, of course, that most everything is sunshine and lollipops when the NFL is in training camp mode. That was one problem for the Cowboys last year, as the team foresaw the jitterbugging Blue as a counterpoint to their steamroller starter, Javonte Williams. ESPN insider Dan Graziano visited the Cowboys’ camp in Oxnard last week, and said that the supporting cast for Williams, headlined by Blue, has been impressive. The three were supposed to be competing for the RB2 role, but it increasingly looks like it will be Blue. During last month’s mincamp, coach Brian Schottenheimer let it slip that it would be the Cowboys’ preference for Blue to win the job.
