True.Point was always a good skater he just wasn't a burner....Roy was a terrible skater but has improved to the point that he is still not a strong skater at all but may be smart enough to compensate for his obvious skating deficiencies.
I am going to have to state this again.......every single player in the NHL has had skating coaches and have taken power skating lessons growing up. This fan perspective that there is some Eureka moment on the horizon by supplying a magical skating coach is just nonsense. Skating is like running, in most cases you either can or you can not and coaches only maximize the finite potential that your particular genetic bottleneck will allow. Some players have such awful technique that there can be significant improvement as they may not have listened to earlier coaches or growth spurts sent their mechanics into the blender. In Roy's case he just seems to naturally have a choppy stride and stiff hips and will need to continue to adapt his game to a skating stride that will never be an advantage to him.
It's impossible to turn a player into a wide track power skater for example if it is not their natural stride. The one thing that can be worked on is what you touched upon with Point. First Step, Acceleration and or Change of Pace. This can be enough to move the skating needle particularly with forwards. It is the one aspect all runners who use some form of sprint are constantly working on and talking about. i.e. getting out of the blocks or a runner with great kick. Hockey is the same it has to be constantly worked upon. The graph noted above does not measure this aspect of skating at all but flat out top speed.
