I started following these sparq ratings several months ago after I read that many coaches are now using the results in their recruiting. I think they are designed to measure overall ability in whatever specific sport the camps are designed for. I haven't noticed yet if high or low sparq ratings has resulted in how many offers a player gets but since its relatively new that could change over time. I think sparq training was originally designed to give players an idea on what areas they needed to work on with their athletic training. Its kind of taken on a new direction though with ratings becoming a part of player evaluation.
It gives you a pretty good idea on how athletic a player is. Now whether that athleticism turns into football talent is another story. A player from Alabama set the all time record a few months ago. BJ Scott from Vigor, who Miles visited last week, also had one of the highest ratings this year.
FYI, SPARQ is actually an acronym standing for the athletic qualities it is supposed to measure: Strength, Power, Agility, Reaction, Quickness.
