It's defensible because it's rooted in data. He shows better than Pouliot at ES, and he is favoured in many categories over Del Zotto. Stecher too, in _fact_, but the influence of his most frequent D partners is there. That is the evidence to back up the opinion. Your evidence to the contrary? I'm speaking strictly in terms of the data.
I don't understand how you can continually, and incorrectly, evaluate Pouliot and Hutton as similar players? Pouliot is atrocious defensively. Absolutely comical.
The questions are:
1. Is a player that puts up a Del-Zotto level offense + far worse defense, better than Del Zotto? No.
2. Do we expect that to change in a significant manner? IMO, no, 24 year old players don't generally see a spike. (Conversion rates may fluctuate).
3. Is a player that is -22 with 22 points appreciably better than a player that is -9 with 6 points (no advanced stats used)? No, the difference is 13 extra GA when player 1 is on the ice. He's helping give up as much as he puts up.
4. Last, does Pouliot's PP work trump Hutton's better ES play? No. ES play should be favoured. Normally, anyway.
Conclusion: Jettisoning Hutton over a worse player in Pouliot is an outright error. Moving him to keep even Del Zotto could be categorized as a mistake. This is less about being OK with whomever leaves, and more about which one should leave first. They are not all copies of the same player.
I don't consider them similar players in what they do on the ice...but they are similar in their level (3rd pairing) and their short comings (defense in front of their own net). If you disagree with that, we will just have to agree to disagree.
Your points vs +/- argumemt isn't really worth engaging due to the limited value of +/-. Who were they playing with/against? How were they deployed. Was Poo's minus accumulated consistenly over the course of the season, or did he have a couple spurts of big numbers that can be explained by injury and being deployed over his head?
As for being 24, which guy are you referring to? Seems this point addresses both guys equally no?
You are of the impression that Hutton is a far superior 5v5 player. I don't agree. Comparable level, sure. But superior? Not over the last 30 games or so. Hutton did have a stretch of very good games earlier but his play jas been on a downward trajectory since. Pouliot started well, then played some horrible hockey but finished the season on an upward trajectory.
Your "data" you are using to support your opinion i am assuming is some corsi numbers. You really need to be careful about using corsi as a definitive indicator. All sorts of variables that can influence those stats, and of course there are always statistical outliers.
End of the day, both are #6 guys on a good team right now, young enough for some improvement but too old to be expecting exponential improvements. You've ignored Poo's versatility (can play both sides + PP) plus probably being ~$1.5m cheaper. I don't hate Hutton but I would move him before Pouliot because I feel Pouliot's strengths are more valuable while their weaknesses (coverage around the net, consistency) are similar.
