$7 million for a player like Bertuzzi is quite pricy but considering the style of game he plays, a blend between Matthew Tkachuk and Tom Wilson, he is more valuable than his production suggests.
Just last year, he posted 30 goals and 62 points in 68 games. While he regressed this past season, he scored 10 points in 7 playoff games which shows how valuable a player like Bertuzzi is in the playoffs.
With what Matthew Tkachuk is doing right now with Florida, a team competing will certainly want to overpay for a Diet-Tkachuk in Bertuzzi.
