The forty-yard dash times are starting to filter in from the Combine and while they’re preliminary and not official, RotoViz is preliminary and not official so we don’t GAF!

I’ve been following along with the great sheet provided by @NEPD_Loyko and have calculated some speed scores for your amusement. We’ll have more combine coverage as measurements continue to pour in. I just thought this table might save you an ice cream headache or two as you watch times come across the ticker and try to figure speed score in your head.
Here are some notable speed scores in case you want a basis of comparison.
