“Real life doesn't fit into little boxes that were drawn for it.”
Last week Pederson “successfully” challenged a play that moved the ball from 2nd and 19 to 2nd and 15, and since they were already at the 21-yard line didn’t meaningfully change the field goal range quotient. This is considered a success because the call was overturned, but it’s a total waste of a challenge since it still cost a challenge attempt early in the third quarter in a one-point game and improved the Eagles’ win expectancy by 0.4 percent. Challenges are better saved for much more high-leverage opportunities like big swings of yards, changing third downs outcomes or potential turnovers, until it gets late enough in the game that you don’t anticipate many more challenge situations.
