Miller will be RFA without arbitration rights. So, unless he’s offered a qualifier from other team, he ain’t going nowhere. He is ny rangers property no matter what they offer him as an extension. Once that extension is near the end, it might make sense to trade him depending on his further development and potential asking price from his camp. At that point he might become a causality of a salary cap. But before that I don’t see any reason to trade him. He is and will be relatively cheap for next couple of years.
