Well he is a center here moving forward, at least for the rest of this season. I certainly have seen a large group of mixed opinions as to where Coyle fits best. But he is a good bit better than the alternatives the Bruins have now at 3rd line C, and for at least the moment Heinen is stepping up and filling that top 6 role, which maybe falls to a Cehlarik or Johansson if Heinen falls
I gave Sweeney a C+. There were better players out there who went at reasonable prices, but I'm not sure Sweeney had a chance (ie Nyquist). I'm broken hearted on Stone, but if the Bruins offered a solid (say better) package and Ottawa said no, then there is nothing you can do. Same is true if Ottawa somehow had this huge prospect rsating on Brannstrom.
On the other hand he did resist some options I thought would have been trainwreck (Simmonds), He made the team faster, and more skilled.
