I wouldn't re-sign Drouin for over 3M x 3. Good luck having this kind of success elsewhere. To me his NHL future is pretty much Colorado or bust, so he should come in at a friendly number.
On another note, I'm surprised (at myself as well) that Granlund's name hasn't come up more. SJ is also a place that would probably be willing to take on Johansen as well, so in effect you can go from Johansen to Granlund for 1M/more per season. I'd assume at least a 1st would have to be included.
He's not perfect but he's kind of a Stastny-like player that would probably look good between the 2 towers of Nuke and Rants. Maybe another Finnish brethren would get Rants head on straight.
SJ has a few other pieces that we could benefit from too, like Sturm for example.
