I like the Old NHL style of line make-up. One winger is a Power-Forward, the opposite winger is a sniper, and the center is the playmaker. A classic example was Clark Gillis-Bryan Trottier-Mike Bossy. A similar Toronto line was Roberts-Sundin-Mogilny. I feel that Marner and Nylander will be two future play making centers. I wish JVR was a Power Forward, but to me he is more of a tall skilled play making winger with average sniping ability. Lupul without the injuries would be a Power Forward. Kessel was a true sniper (with a dis-interest in playing with any defensive accountability). Panik may develop into a second line Power Forward. Toronto needs to develop or trade for or draft a true sniper for the power play. A successful team needs a power play that can operate between 20-25%. This is where a true sniper is needed. I do not see any of our prospects developing into pure snipers. The rebuild will take a few years and a sniper will have to be acquired or developed.
With the focus in the NHL going to skill and speed, Power Forwards may become a rarity. Top two lines may become built around a play making center, a sniper, and a winger that is a combination of both skills and is more defensively responsible. With the focus on speed and skill, smaller skilled forwards in the Top Six will be more common. Larger skilled forwards will still be preferred but there will be more room for smaller players. The bottom six will be the area for larger defensively responsible grinders. It has been mentioned by another respected poster that Babcock likes to have at least one defensive responsible player on every line.
To me Patrick Kane is primarily a sniper and also a play making winger. Mitch Marner could be a Patrick Kane or a Claude Giroux.
