I actually think they could get a pretty decent return for Edmundson. Playoff teams will want his physicality - which he can bring if he wants to. I think he is also viewed as a "steady" veteran defenseman. They definitely would get a 3rd rounder for him, maybe even a 2nd?
Jenson also could bring a decent return. He is a good skating puck mover and I think they at least get a 3rd round pick for him - although his $4 million contract for the next 2 years will probably be a bit of an issue. If it were just in the $3 million range, I think he would be attractive.
So, I think Edmundson definitely gets traded and Jensen stays.
