I don't know. Hard to tell from the angles, but he impeded his contact for at most a half second. No way was he going to be able to change directions in half a second to come back to a ball that was THAT underthrown. I think it might have been uncatchable, the guy had only just started trying to reverse his momentum and he had no hope of slowing all the way down and coming back to it in that short a time.
I don't think the missing of open receivers was as frequent as some think. I think the issue, for us, was the combination of all three things you mentioned. Either nobody got separation, there was separation and Nico overthrew or didn't see the open receiver, there was separation and Nico threw a perfect pass that was dropped, The OL didn't give Nico time to find a receiver, or everything worked together and the play was called back due to a penalty. As for the Oline "fixing itself", I would say the jury is out on that one, as we will have mostly new starters next season. I'm not willing to proclaim them trash without first seeing how they perform together(and who we end up with).
