Nick surviving this far is huge for him. It should get him a good shot on the practice squad. Like some have said, his goal is to make it as a punt returner - but the Redskins also have a very old slot man (Santana) that needs replacing soon. Hopefully Nick's edge as a slot man helps him beat out Skye Dawson. Richard Crawford's injury was huge for both those guys.
Both will need to beat out, however, Chris Thompson for the job of punt returner. Thompson has been a bit of a fumbler, but does probably have more breakaway speed than Nick.
I don't think Nick ends up making it, but I do think that he ends up making the practice squad with a real chance at promotion if the returners falter at all.
