Every year the National Football League invites 335 draft eligible college football players to a scouting combine
Question:
Every year the National Football League invites 335 draft eligible college football players to a scouting combine where they participate in a variety of drills and exercises. One of the more popular drills, called the 40 -yard dash, is the time it takes each player to run 40 -yards. We computed the average 40 -yard dash time every season from 1990 to 2016 for all players at two positions: wide receiver (WR), who receive passes from the quarterback, and defensive cornerback (DC), who try to stop the wide receivers from catching the ball. These data are presented as a spaghetti plot in Figure 2.90.
(a) Describe the general trend of both positions. Are the players getting faster or slower?
(b) In 2016 which position had a faster average 40 time?
(c) Does one position appear to be consistently faster than the other?
