What is the probability of Blue being misused? Does he have the frame to withstand the role of a starting RB?
Blue is not the same size as Gibbs, whose 200 LBS is packed into a 3-inch smaller frame, significant for a RB.
What about his propensity to fumble? Is that going to improve against much larger, quicker, and ferocious opponents than in college?
How is Blue anything more than a specialty back, the pass-catching speedster that takes advantage of a worn-down defense, courtesy of the more rugged starter?
I'm not opposed to drafting him here, but he is not the solution to the Cowboys inability to run the ball. The opportunity to acquire that guy faded when the lights were turned off after day #2.
