Hopefully players learn a lesson from Klingberg. You have such a short time to make money as an NHL player that it makes sense to accept a large, long term offer instead of trying to gamble on yourself for a year. If Huberdeau never accepted Calgary's offer he'd probably be looking at a 5 million/1 year show me deal with another team this year. Klingberg's mistake will probably cost him close to 40 million in career earnings.
If he didn't sign with Calgary when he landed, he would have been moved at the TDL. Whether he regained his FLA form, who knows. Unknown what the market would have been for him. Not many big names hit the UFA market.
Unless the agent was sure "via some tampering" with other GMs, he really should have pushed Klingberg to sign with Dallas.
I mean, it was a flat cap. So, easy enough to go through capfriendly to see where each team stood. Then estimate the amount RFAs were to get from their own team. That leaves a better snapshot of who can afford $8 mill plus for Klingberg, if any. Those with the cap space, then have to ask if a RHD is a top need for them. Cause, moving contracts was very expensive to do the prior couple of seasons, so no surprise teams not that interested to do it.
