I think Hagg gets a chance before Sanheim. I feel like Sanheim will get the Morin treatment next year. Plus doesn't look like Sanhiem is getting the tough minutes yet offensively or defensively. From what I read he gets stapled to the bench late and they role out Morin and Hagg regularly. I know that's not Sanheim fault, but I feel if Hex wasn't on board with it there would of been changes by now. Plus if Hak is still here, I can't see him pairing Sanheim with Provy, Ghost, or Morin yet.
If Hagg continues to have a strong season mentality I can see Hex giving him the 6th D role next year, which at this point is his future role anyway. And unlike Sanheim, I really don't think it will hurt his development if he gets just Manning minutes.
