It's a GREAT problem to have,
Doughty
Roy
Durzi
Walker
Spence
Grans
Clarke
With the exception of Doughty, and Walker I think everyone is what 24 and under, 25 and under? Not sure on Roy either, but on that list of what....7....you have 3 spots, one is filled with a future HOF (albeit older) One is a rock defensively, two are good puck movers, you have 4 proven NHL players..out of that 3.....you have Clarke who is going to replace Doughty at one point, so your options really are, Doughty/Clarke, Roy, and then one of Durzi, Walker, Spence, Grans.....
What's the right answer, no one freaking knows......but opportunity cost plays a part, if you can get a missing puzzle piece for one of those 4, Durzi, Walker, Spence, Grans, I think you have to do it, no matter which of the 4 it is...
