Not even going to address anything to do with McDavid moving forward, TBH it just feels like trolling.
It sounds like you are arguing that I am saying Abby and Bertuzzi are equals, I am not. I am saying that the Wings made a mistake with the Abby's contract (and please dont make this a Holland thing, I'm not a person ho blindly bashes Holland) and I dont want them to do it again with Bertuzzi when it actually matter, it can't hurt to see if Bertuzzi can do it one more year and/or to play hardball with him. Year after year, we see players have a good season or two, only to regress. Abby is a perfect example of this. Looking at Abby's career PPG is pointless, he fell off a cliff, but you know that.
Abbys best two season were 2014/2015 & 2015/2016 (age 27/28) and he scored between 0.51 PPG and 0.62 PPG. This is not far off from Bertuzzi if your stats are correct.
Is Bertuzzi better then Abby, yes. I believe so, but I cant criticize Yzerman for being cautious of the cap. Look at the situation Yzerman just left. I'm sure if he could go back in time, he would love to pay some of those middle tier players slightly less money, so he could have kept them. Bertuzzi is kid I want to see in our lineup for years to come, but he is not elite, and players who are not elite and are paid on the higher end of the pay scale tend to be traded down the road in order to preserve cap space. I don't want Bertuzzi to be a cap casualty down the road. You can compare cap management to "preparing for the zombie apocalypse" if you want, but players like Bertuzzi matter to me, and I'd rather see Yzerman play hardball with him now so we can keep him down the road, opposed to Yzerman overpaying him now, and then dumping him in 3 years so we can stay under the cap.
To each their own I guess, if you think caring about that is stupid, you have that right.
