Yes it was a 10 game sample if you try and translate it as "which MTL dman is the best offensively" that's not what it tells you.
What it was telling you is that MTL was generating a lot more offense with Hutson sitting on the bench back then.
From my viewings, it was because Hutson was trying to do too much himself. It made the offense very easy to stop and very predictable, as you would just protect the shooting lanes and keep hutson to the outside (especially with him not being a shooting threat).
Now, he plays much more within an offense, much better without the puck. And it makes him much less predictable and much harder to defend. Leading to much better offensive results.
You can praise Hutson for his impressive growth and development, or we can lie to ourselves about the past and pretend he was this all along.
I'd rather give credit to the kid for his improvement
