By itself, not really a whole lot. Maybe nothing at all. But you have to ask the question why a guy is moving teams. Like, why did Tampa draft him 19th then trade him after a fantastic final year in the OHL and a good rookie campaign, for the 37th pick? That's worth examining (I mean it's beating a dead horse now, but just for the sake of argument).Mike Silinger switched teams almost every year to the point where it seemed like he’d played for every team in the league. It didn’t make him any less of a valuable depth player.
I really don’t see what moving teams has to do with anything.
Why was Arizona so eager to target and acquire him, but then willing to flip him just a year later (because they really wanted Stepan, but also probably because Tippett didn't like him that much and whatever else; they wouldn't give up Chychrun but were fine moving him)?
I mean really, being traded twice by 23 isn't a big deal in itself. It's the "read between the lines" aspect of it, where I think it's being implied that at least part of the reason he has been moved twice was because he wasn't viewed favorably by either the coach, GM, or both--which may be the case again, with us.
