My response was not really in regards to your reasoning or value, and I actually multi-quoted two other posters, but for some reason yours was the only one to come through, (most likely user error on my part, all the options on these boards still confuse me
so sorry, I was not trying to pick on you specifically, (except for the dumba idea part, I was definitely teasing you for that, but it was all in fun, so hopefully you didn't take it too personally).
I find the idea that we are speculating that a 22 year old defensman that had been poorly developed was probably already at his peak. That was the take-away I was trying to (and likely failed) to relate.
Jokiharju doesn't have a ton of value right now but he has shown flashes and has the pedigree that he is worth a lot more on the gamble of keeping him and letting him further develop than moving him now for a reduced return, imo.
