Fair comment, thank you. But I'd ask that you consider that:
1) Most consider C to be the most important position you can fill.
2) Worth can be considered in a number of ways. One way, which is how I am suggesting, is that it provides the Leafs with a superiority beyond just the value of the player.
3) With Toews, there is no weakness in the Leafs F grouping. There can be two superior offensive lines, a strong defensive line, and a quality 4th line. No other team in the league would be able to match what we could offer.
4) The deal is advantageous to us regarding Cap compliance. We'd be able to accrue money that could be spent at the deadline.
5) Any injury, any (!), at C is covered more than any other team in the league.
6) Our D corp is not affected by this consideration this year. Sandin would be, at best, our 3rd LD. Dermott/Lehtonen adequately fill that position this year and next.
7) At some point you have to make a choice as to whether this is a good time to go for a game changing decision. It's perfectly arguable to view Toews as a player not capable of moving the needle sufficiently to make this type of move. I see it as a golden opportunity. Your 3rd line is strengthened, your PK is strengthened, your C depth is strengthened, your playoff experience is strengthened, your motivation is recognized, your most talented group is/approaching their most productive years, your D is stronger than it has been in years, you've got a 2 year window with the same players (minus replaceable players)...send a message. Tell this group you believe in their abilities and give them the push by saying 'fellas, we can do this'. See: Raptors, Kwai Leonard.
8) Matthews, Tavares, Toews, Thornton, and the options that follow.
I want a Cup. A two year window of this potential group is better than anything I've seen since the 60s. At least consider it, before dismissing it with bland "it's a waste, plain and simple".
