Is a 4.7 a good forty yard dash time?
that’s a OK time but you should be aiming for at least a 4.5 the whole thing with the 40 time is simple as knowing how to run so you should spend your time this summer with stack team or running down hills as fast as you can that will get you legs get use to moving that fast you have to find a steep hill that’s how i did it i ran a 4.6 in 10 grade by my senior year i ran a 4.34 at the VA tech combine believe me you have more than enough time to get your speed up just keep working at it and don’t get discouraged
