Outside of the core four of Larkin, Seider, Raymond and Ned...I would listen to offers on anyone. You would have to give me a lot to get Bert...overpaying even...but I would definitely be open to dealing him.
What would your ask be for Bert? If a toxic asset with health issues like Eichel can fetch a top six F, a decent prospect and a 1st and a 2nd rd pick...I would think Bert should net something in that range
