Every year there are obviously multiple posts about why a certain player is really good or why a certain team is really good and as a part of the justification "track times" are mentioned. There are then a subset of folks on here who will tear those comments down with arguments based around "football speed" vs "straight line speed" etc.. The debate will then turn into a discussion around how valid track times are or are not in predicting the success of a football player, and if does matter, how much does it vary at different levels of the game.
