I would say that Frondell is a decent, slightly above average skater, but optics could be distorted as he plays in a generally better league against some fully developped players. He skates well enough for his tool-set.. Desnoyers is definitely the best skater out of that bunch and would even put him at "above-average +" comfortably, with room to improve with strength, but like Jay Gray said, slightly underwhelming for a centerman. McQueen is a lumbering skater and the worst of those four; He was drafted out of AAA at 6'3 and has slowly grown since then to being almost 6'6, where you can tell the extra body height and length is still very much affecting everything from his deceptiveness to explosiveness. Pair that with a back injury last year and then a lower-body injury this year, he's got a mountain to climb to get on the right side of being an OK skater. O'Brien is also average at best at the moment. He's a guy who needs to work on his base-line skating mechanics, but also has a lot of room to grow in the strength department, so might have the most upside, in terms of improving skating, out of those 4.
