The 'defensive defensemen' does not exist anymore. Need to be able to make sharp outlet passes under pressure (Siegs cannot, just my opinion). I'm not bright enough to quibble about advanced stats, but Siegenthaler for 1.5 seasons has been mediocre. Only thing helping him is his handedness.
Neither of their contracts matter much. On a human level, I will say, they both deserve to have NHL contracts, but I don't want to be the team paying Siegenthaler anymore. He's not worth anything more than the 3.5-4 he's making. Send him to Ottawa, idc.
