He was one of the Avs' saving graces this past season but not likely he'll be a 49-point guy again. As has been stated, the Avs center depth is dire so the only way they are going to trade their second best natural center is if they address that gaping hole some other way, or use Soda as a makeweight in a deal for that solution.
If the Avs retain, you have a quality veteran two-way center who should have no issues being a 20 goal, 40 point mid-6, two-way center for probably $3 million or less and who will come off the books after next year (before he's too old to be effective). That will definitely have value on the market and interest among GMs even if he isn't a sexy name here at HFB.
