Agree that they could have done that. But Johns would have been the #1 then, with no Seabs, and no Duncs due to injury. Or the #2, actually, and Hammer would have been the #1. I don't see the Hawks even making the playoffs last year if that were the case. They would have been icing 2 top 6 defensemen for the first 15 games of the season... I know Duncs wasn't out super long, but he also wasn't his usual self until about half-way through the season.
The D would have consisted of Johns, Hammer, Sved, TVR, Rosi, Gus, and Rundblad for the first 15 games, and then the same, but with a non-100% Duncs instead of Sved, Gus, or Rundblad until about the all-star break. I honestly think they miss the playoffs completely last year, if that were the case. I guess they had Daley too, which probably would have been ok, had he been utilized correctly.
