O'Connor scored a shorthanded goal and added an assist in Wednesday's 6-5 overtime win over the Sabres.
O'Connor's two points helped the Penguins erase a 3-1 deficit in the second period. He's received some top-six looks but has spent time on the third line as well, which isn't ideal for his offense given the Penguins' shaky depth. O'Connor has three points, seven shots on net, four hits and five blocked shots over five appearances and will have a lower ceiling as long as he remains out of contention for a power-play role.
