Under 4.5 well i am 185lb defensive end playing semi pro, i run a 4.8 and nothing gets in my way, i at least get 2-4 sacks a game basically what it comes down too is the size of your heart.
Depends what grade your in It's not bad for a high school defensive back.
A 10 yard dash time is really not a good judge of your speed, the distance is too short. A 40 yard dash is what you need to get a good estimate of your abilities. but I'll give you time for both 40 yard dash-between 5-5.8 seconds 10 yard dash-between 1.3-1.5 seconds

Eli Manning's 40-yard dash time is 4.92.
40 yard dash/10 yard dash= 4 What ever the time you got for the ten yard, you multiple it by 4. It could be an average of your running time per 10 yard dash. Sometimes for several runners, they would feel worn out by the time when reaching the 40 yard mark.
