He was fine with coming to Buffalo and his effort was always very good.
No doubt that by they time Adams came in to replace Boterill and was embarking on another rebuild, he wanted out. Can't blame him, Eichel, Risto, Montour, or Ulmark.
Reinhart was always a good player, even as a young kid you could see the talent and skill, he just needed to get stronger and more experience.
He is in his prime right now at 27. He left Buffalo at 24, just at the start of prime years for a forward.
Mitts wont score 50, but I expect a breakout year from him next season if he stays in Colorado.
