Ah! Thanks for clarifying. Again, agreed that DD doesn't really belong on this list. He finished 2nd in the skating comp last year.
Desharnais has mediocre top speed, especially compared to others on this team, but he has pretty good acceleration and is faster than most when it comes to things like skating around the corner. Desharnais is far from slow, he's just slower than you'd expect from a player of his size, but his overall speed is just behind the team's elite skaters.
When it comes to dump and chase footraces, Desharnais would be far from the first choice, but he's relatively agile overall.
