Where is Mark Helfrich going exactly?
I don't see a major college team looking at him as a viable candidate, considering how things ended at Oregon. Good player coach and meshes well with Nagy (I mean, shit, he managed to get along with Chip Kelly), but he doesn't appear to be HC material.
As for Chip Long, as a ND fan, Long has upped his game recently, but I have been a bit perplexed by his play-calling at times. His run calls are generally frustrating. ND has a homerun threat in Dexter Williams, yet they almost never seem to attack the perimeter in the run game, and go with really predictable inside dives. In terms of passes, he's been excellent calling the right plays. Running, I hope we see a lot better. ND will need to be a lot more creative in run calls against teams like Clemson or Bama.
Either way, don't see it happening. Long seems like a guy who is destined for a HC job soon. I don't see him jumping ship to another coordinator position, even if it's going from college to NFL.
