That's the important thing to remember. It isn't really about foot speed especially for skilled players. It's about positioning and decision making. The puck moves faster than the feet. For your less skilled players speed becomes a bit more important I think as a good chunk of those shifts are going to be dump and chase.Maybe he can picture himself as a good fit in Rick’s system with a summer of weight training and skating work. In a well functioning system with everyone playing their part there is room for guys to not all be Donovan Bailey. He is someone I can see playing fast as in snappy and decisive as opposed to being fast.
But you need a minimum level of speed and fitness. Right now that is where Boeser is failing. I don't expect him to be a fast skater but you see glimpses that he can have a decent skating pace. But it is only glimpses. That's either a conditioning thing or he has trouble getting his legs to fire due to injury (back or hip). Nothing right now suggests injury issues so I lean towards fitness. He sorts that out he can be an effective player because, in general, throughout his career his positioning on the ice has been very, very good.
