You can't even get the cap hits right. The core 4 were 40.5m per, not 42.5m. Hyman was 5.5m per, not 5m. What a coincidence that one went up and one went down; both to your argument's benefit. As for the misleading calculations, Hyman was the poster boy of playoff underperformance, underproduction, and lack of conversion while here. So if you're now praising him and broken over his loss, that means you'd have to acknowledge one of two things:
1. Playoff production is heavily dependent on the situation a team experiences, the opponents they face, and the position a player is put in, and Hyman's increase is primarily a result of Hyman's new position and the situations Edmonton has faced being much more conducive to production.
2. Players can individually go from one of the worst playoff players to one of the best playoff players at the drop of a hat.
If 1, you render your contextless comparison pointless. If 2, you contradict your attempts to get rid of players based on any perceived lack of playoff production.
