No, but he came to his first camp out of shape, then injured his knee and hasn't been anything more than a mediocre bottom-4 dman. His buyout was also a single move that the team could make to get under the cap. Smith or Staal, while definitely more deserving of buyouts in my mind, wouldn't get us under the cap. So, I think the choice the front office had to make boiled down to a couple options:
1) Buyout Shattenkirk
2) Buyout both Staal AND Smith
3) Buyout one of Staal/Smith AND move another ~$2M in cap
Option 3 is the most preferable from my standpoint, but that all depends on what other teams are offering. I don't think the front office wanted to part with assets to move a contract, or take pennies on the dollar for Kreider while dealing from a position of reduced leverage.
