Sure, and my argument with the original post was the proposed timeframe of "in a heartbeat." The time you're talking about hasn't yet come -- need to see how he does in a greater role, how his next contract is looking, etc. I expect this year will be about seeing if Kadri's as good as those advanced stats suggest, if he can become a leader on the team over the next few years. It wouldn't be bad to have someone in that role who came up through the organization (beats trying to buy 'leadership' on the UFA market...). And even then, if the contract demands exceed the value wildly -- yeah, move him. But the fact that he won't be an RFA forever doesn't, on its face, bother me.
My underlying discomfort is with this idea of planning to be horrible to the extent that it becomes self-defeating. I think good teams hold on to the good players they develop, and don't go out of their way to sustain terribleness. After all, the Blackhawks had a mid-20s Patrick Sharp on their roster the season they drafted Toews, the one before they drafted Kane.
