Next time your dad brags about the glory days of the NFL or how basketball's not the game it used to be, show him some old tape. It might be hard to contrast eras, but it doesn't take much comparative analysis to see that Dick Butkus was slow as fuck.
Another example is Bobby Morrow, an Olympic sprinter whose pedigree and gold medals might impress you, until you peep his time. Morrow's 10.2 second victory in the 100 meter was enough to win a gold medal, but it'd be good for, like, third place in this year's Texas high school track and field finals. Still, a powerful moment in whitey athletics.
