Antonio Gibson will likely leave via free agency, leaving Brian Robinson as the lone, capable, starting running back. But, in the fourth round, a value like Braelon Allen is impossible to pass up, giving the Commanders a nice one-two punch.
Allen stands 6-foot-2 and weighs around 240 pounds, giving him a massive frame that he knows how to use. He is a punishing runner between the tackles, but watch out, because his straight-line speed is definitely there when he makes it into the second and third levels. Allen has the potential to be a real workhorse at the pro level, but will compliment Robinson very well to start with.
Finally, in the fifth round and at pick 139, the Commanders add another guy to their secondary in Michigan's Rod Moore. This is yet another pick where I feel like the Commanders got incredible value, as Moore is one of the best all-around safeties in his class.
Moore is great against the run and in pass coverage, making him a valuable asset to any NFL defense. He has the ability to play either safety spot and play it well. This Commanders defense could look remarkably different after having added Moore and the previously-mentioned Arnold to their secondary.
