I would be more surprised if he doesn't play for them next season.
Now... will people let him have a rookie year or be all twisted up if he "only" scores 15-ish goals and 30-ish points as a first year NHLer? That remains to be seen.
That kind of production/pace worked for Krebs this year and Cozens in his first full year, so while I think Quinn could be more of a 20G/40P guy, that's a perfectly respectable rookie season and I wouldn't be twisted up about it at all.
