Time for a hard dive into the tank (though the organic tanking of the last three games has been damned impressive in its own right). To that end, I'd like to say the following:
Trade Rakell - Value still high, use last retention slot to move him if necessary
Keep Karlsson - Nothing will accelerate the tanking more than his lazy, pylon-like defense
Trade Acciari - His role on this team is useless
Keep POJ in the lineup, continue to pair him with Karlsson
Keep Rust - providing a whole lot of nothing, better served trading him when his stupidly provided no trade clause expires after the season
Bring Jarry back up - Blomqvist isn't ready, they might be able to salvage him for next year. Jarry is already cooked, so let him get torched for the rest of the season
Leave Sully in place - this will be most critical in assuring losses moving forward, this year and for next year's tank
I think doing the above will drive the Pens to a bottom three finish this year, and they are well on their way to a bottom three finish next year
