IMHO McKenna makes the youth rebuild angle very attractive. On one hand we want to win now (also taaractive), but on the other hand we want to win when McKenna hits his prime. Balancing both those wants is tricky, but that's the situation we're in now. Good thing we have a GM who's bold, and that's what we need right now (or so I'm told

).
As far as the bolded goes, that's not the only factor to base decisions on. We have picks in other rounds, we have 1st round picks again in a couple of years, we have assets we can trade for high picks and McKenna is still probably at least 4 years away from hitting his prime so we have plenty of time to get ready for that.
