Draisaitl also has a wide wingspan. Ekblad was 6'4 at the combine but had the same wingspan as Draisaitl. People use Kopitar as a comparison for Draisaitl and I think that still applies even with the height difference. Height is overrated as a physical stat.
Agreed, height is fairly overrated. Arm length, leg length, how a person is built, along with a host of other factors are also important factors to a person's size.
People also over-simplify/generalize weight listings as well. Malkin at 200, and Hossa at 207 are some of the strongest players in the game.
