Sheesh, I'm starting to look like a real idiot (that is if I didn't already).
I swapped the Blues #1 pick for the Sens #1 pick early in the year when Ottawa was just out of the playoffs (the deal involved a few other minors things, most notably cash going the other way to Ottawa). While I figured they would probably get in the playoffs, I didn't figure they would win the cup. If they do, my 1st goes from #16 overall to #30, and the Sens will end up picking just in front of the Blues with their original pick. To add a little insult to injury, they'll probably take the player the Blues wanted.
All my draft scenarios of who will be available at #16 are starting to look moot.
