I don't think Hurst get's a big pay day by anyone. Why would anyone pay someone who isn't a starting caliber LT/RT and only a guard who while solid isn't special? I don't think we even have a slight chance at a comp pick when it comes to him. I think he stays at a decent price.
Matt Skura, yes, Matt Skura is a very important player to this offense. As soon as they replace Eluemanour with him, things have progressed so much better for this offense. He has been a big reason why we have seen dramatic improvements from them overall. I think him using pulls has a lot to do from the fact that Hurst and Skura excel in that regard. A lot of our most successful runs come from Skura/Hurst pulling into the outside run. It even plays into Alex Collins and Buck Allen strengths who move well in space and excel on outside runs.
I don't think blocking TEs have also been a reason why they've done solid as well. Protection varies from who your opponent is and where they feel the need to slide protection to. Stanley can more then hold his own in pass protection but Howard has been a bit of a liability in that aspect, I have seen plenty of chip blocks and added protection on that side. I don't think Skura and Hurst are alone in that aspect.
