But would Maroon want to go back to either team? Edmonton seems like a natural fit but maybe he wants to stay closer to the Midwest the rest of the season or something.
And one of the teams he "wants" to go to, would have to want him in return. Maybe the Blues tried but couldn't find a suitor. Remember that they also tried trading Jaskin before waiving him and couldn't find anything. Sometimes fans overestimate the value of these 4th line guys... Maroon's foot speed doesn't help his case in today's game, nobody wants to get slower. Everyone wants to get faster. If I recall, aside from the Blues, Devils and maybe Oilers - I don't think he had many teams trying to sign him in the Summer.
So there's lots of variables here.
