Please rate a 1.8, 10 yard dash for a high school defensive end?

Would a 1.8 seconds 10 yard dash for a 220 lbs. high school defensive end be considered outstanding, "get-out" quickness for the position?
Does anybody have any 10 and 20 yard dash standards for 13 to 17 year-old males? I'd really appreciate getting them.
