Marcus Pettersson is a top-four defenceman, and there's going to be a number of suitors. Still, he's averaged 19:25 in even-strength ice time while the team's been a mess and has anchored Pittsburgh's penalty kill.
On a better team, he could be a real star. At a more-than-reasonable $4 million cap hit, and with only one salary retention slot remaining, the Penguins and Pettersson are the ultimate rental candidate for contenders.
Drew O'Connor, of course, brings value in a different way. The towering 6-foot-4, 209-pound forward, at 26, was a breakout 16-goal scorer this past season, a physical presence who can score, and has taken on increasing penalty-kill responsibilities.
A pending unrestricted free agent this summer, O'Connor's combination of size, skill, and affordability has made him a legitimate trade target.
