Honestly, I'd rather watch this core ride off into the sunset in this jersey than ever see them traded. I personally wouldn't have wanted to see guys like Sakic and Hejduk play in another jersey in exchange for being competitive sooner. From a cold-blooded strategic standpoint, the Pens made the wrong move not trading Crosby years ago, but ask any Pens fan if they would have wanted to see that happen in exchange for a quicker rebuild that may or may not even succeed. I'll bet if you posted a poll in the Pens forum asking that question the results would surprise you.
Rebuilds always happen eventually, and statistically, most of them don't ever result in a Cup win.
