Provorov averaged 0.52 points per game last season (36 points in 69 games), his highest total in four NHL seasons, with Matt Niskanen on the right side as his defense partner. But with Niskanen retiring Oct. 5, there's no clear choice for a replacement.
Philippe Myers could be the leading option. He's a right-handed shot, tied for second among NHL rookie defensemen with a plus-17 rating last season, and his three goals during the postseason tied Provorov for most among Philadelphia defensemen. Myers is a restricted free agent.
Other options could be Justin Braun, a right-handed shot who played mostly on the third pair last season, and Erik Gustafsson, who signed a one-year contract as a free agent Oct. 12. Gustafsson, a left-handed shot, was sixth among NHL defensemen with 60 points (17 goals, 43 assists) in 2018-19 playing the right side as Duncan Keith's partner with the Chicago Blackhawks.
