If someone put a busted up ferrari for sale and wanted full retail price, they wouldn't get many offers either.
My point is, by all reports, Adams asking price prevented him from getting serious offers this summer.
This is a good return...considering the circumstances.
However, a good bit of those circumstances (i.e. making the trade in season, limited bidders, etc) were self inflicted. Here is what we've been told via various reports:
1. The team was unwilling to share medical info until LATE into the process (either shortly before the season started or shortly after, IIRC).
2. Teams noted that the asking price this summer was, essentially, for a fully healthy Jack Eichel, which he was never going to get
These are unforced errors by a rookie GM which likely reduced the return. By limiting his trade partners by not getting medical info out and not having serious talks by asking the moon, he put himself into a bad position.
Adams is a bad GM and handled this badly.
You are never going to win the trade when you trade a top 10 NHL player.
There's only degrees of losing.
Adams tried to win the trade this summer and got .50 on the dollar instead of .75 on the dollar he could have gotten with more bidders.
