If Sanderson continues to improve as he gets comfortable, and gets 45-50 points, he should win the Calder.
However, because sportswriters vote rather than knowledgeable people (GMs, scouts, etc), a 60 point bad defensive Beniers would probably get more votes than a 50 point rock solid Sanderson.
I like Pinto a lot, but he won't outscore Beniers in the end as Beniers gets every #1 opportunity to score with Seattle. The Phoenix guy is a no-name, will probably drop off. Guhle is decent, but he'll probably end up with 35 points (good) and a -25 (bad).
If Logan Thompson keeps it up, he could very well win the Calder. But he will be 26 at season's end, this year's Bunting, shouldn't even qualify at that age.
