I understand you want to see a more friendly, jovial atmosphere, and your example using Dave Steib is a nice story, no doubt. Now, because the team is well off there are other little bonuses that can be added in that has to do with the travel arrangements, accomodations, training facilities, etc, etc. Those can be used as trade offs to get them to come down on their price a little bit. But in a Cap world, we are stuck with a budget, and the cost of being a team that spends to the cap is that there will always be some form of nickle and diming as you put it.
And I really think you are putting too much stock into the arbitration number. You NEVER go in as management giving your "best" offer. Just like labour alway never goes in with their "bottom line" offer. I've sat at both sides of the table. This is very normal.
As for value vs Prust. Prust was a UFA, Eller is an RFA. You rarely, if ever, get an UFA at the actual value, especially if they are coming from outside. I don't think it's really fair to compare those situations, or players.
It just isn't all black and white. It's 50 shades of grey...which is appropriate as we seem to be into a little S and M with the way we torture ourselves over these things
