There aren't many on the market, since most teams that have these assets hold onto them. However, Elliotte Friedman dropped a bombshell today indicating that one could be coming available.
Philadelphia's Ivan Provorov has all of the tools needed to be a fantastic piece for any team. He hasn't been a perfect fit in Philly, but with the right structure and teammates, he could very well be a top-pairing defender.
At 25-years-old, and locked up through 2026 at a reasonable $6.75-million annually, Provorov would be a dream acquisition.
