Columbus has a lot of cap space and a lot of guys signed long term. Perhaps a bit much for Dubinsky but they could afford it to keep the main cogs of their team together for the next several years.
I am a huge Dubi fan as you all know, but I do agree 6M per for 6 years a bit too much. If we had both Dubi and Cali at 12M cap hit, we definitely not making it far in the playoffs. Malkin/Crosby make a bit more than that? 4M more? That's just crazy.
