Sure. The extension of puck moving all the way to the O zone. Most offensive Dmen still don't score a lot of goals. They collect a lot of assists. But regardless of how they score, or how much they score, it shouldn't come at the cost of playing defence. Prevent/block the shot, recover the puck, move the puck out of the D zone with possession, maintain the O zone, pinch, shoot/pass. What have I missed?
A Dman who scores 40-50 pts but is weak in his own end is only half a Dman. Another one who hits and blocks shots but can't retrieve the puck or get it out of the D zone is also only half a Dman. IMO Some will do those things better, at a higher level than others. So we will have 1st, 2nd, 3rd pairs.
