Doesn't have to be Detroit, really doesn't matter what team but the cost to retain approximately 550,000 is a 4th
The cost of retention is determined by four things:
1. The size of the retention.
2. The length of the retention.
3. How many slots are open for the retaining team and how many do they need for other purposes.
4. How desperate the asking team is for the retention to be made.
The amount in dollars is absolutely NOT what decides the price by itself, in fact it is the least important of the four items.
A simple look at the Detroit roster would have told you that they have five players they're likely to trade and that three out of those five have a cap cost that may warrant retention to get a trade done. You'd also have seen that they only have two slots open this season.
Detroit retained $220,000 on Savard for a 4th the last time they retained. You're asking them to retain twice that amount in a year when they don't have any slots to spare for the same price.
