In general to estimate 40 yd dash times from 10 yard dash times you can do the following: For athletes under 200 lbs. assume a low of 2.8 seconds and a high of 3.0 seconds added to the 10 time. For athletes 250-350 you can add 3.0 to 3.4 seconds to the 10.

Jeff Demps also ran a 10.01 100m, not 10.1. Michael Bennett ran a wind-aided 10.00 and a 4.28 at his pro day. Darrell Green ran a 10.08 and is one of the guys rumored to have run a “4.1” back in the day….r/nfl.

What is a good 40 yard dash time for a 17 year old? Generally speaking, a 4.5 time for the 40 yard dash is really fast for a non-track high school athlete. Track stars are in a class all their own. For non-track athletes, a 4.6 time is really good, 4.5 is excellent, & anything less than that is blazing fast.

Average is 5.2, good 4.9, excellent 4.6. Anything over 5.5 is not so good. This is from a coach who has timed 100’s over 20 years. Your height and weight are good but have no bearing on your 40 time.

40 Yard Dash

According to a five-year NFL combine report, wide receivers and cornerbacks had the fastest average times at 4.48, followed by running backs at 4.49.

Bo Jackson is the fastest running back of all time. He is also known as one of the greatest athletes of all time. He played not only in the NFL, but he played major league baseball as well. Jackson could be considered an unreal physical specimen at 6’1″ 227 lbs.
