are you saying that there is a chance of trading a "crown jewel" (if I take out the double negative), or with the qualifier "necessarily", that it is necessary that he trades a "corwn jewel" at a higher point?
IMHO, there is no rush to move any of the young Ds before the return for Savard is maximized. Then, a decision on any of the prospects will be easier to take with more games to base a decision on.
