The Weak Foot Coefficient


Coerver Colorado places a great emphasis on developing the ability to use the weaker foot as naturally as the dominant.  We “teach to the weaker foot” through ball mastery, moves, striking the ball, driven balls, and passing exercises. All of which are stress the needed habits and confidence to not only use the weaker foot in easy positions, but also when it matters most. Another feature that brings attention to the weak foot first touch is our Juggling Progression and the weak foot proficiencies it takes to move up the ladder of levels of first touch skill.

We test juggling, shooting for power and serving a still and moving ball for distance and accuracy.  Now we are using those tests to create an indicator, which we are calling the Weak Foot Coefficient, or a simple measure to understand the ability to use the weaker foot.

“Juggling makes every touch better” and those who complete our Juggling Progression through “Body Parts Juggling” have wicked-good ability to control a ball with either foot.  So, the coefficient includes a component that awards points based on reaching various mileposts in completing the progression.

With the other two tests (Power & Distance) we are looking at two things to build up WFC score.

1)The first is the difference between the weaker foot scores are to the dominant foot scores.  Getting the weaker foot total to 90% of the dominant foot one seems like a realistic target.  Getting to 95% or better is an indicator of real proficiency.

2) How a player compares within his or her age group based upon all players in that age who attended a 2019 Summer Camp. The WFC uses an element we called the Absolute Value. The ABS is a comparison of how Center of Excellence or Performance Academy player compared to the top 10% of players scores in the assigned category in the 2019 Summer Camps. That middle score is a “1.0.”  Other players’ scores reflect how much a player is above, or below, that score.

All these things get bundled together in the Weak Foot Coefficient.  Our initial thought is that a score of 5.5 or above indicates the player’s ability to use the weaker foot is very strong.  4-5 to 5.5: well on the way.  Below that: it’s a work in progress.

Our recommendation to parents is that they focus more on the components of the WFC more than the number itself, starting with the dominant/weak foot differences and the player’s juggling progress.  The place-within-the-group components contain factors tied to age (e.g. size and strength) within the group and won’t be fully reliable before U14 or U15.

We’ve seen the results of this emphasis – The best players can make the use of their weaker feet so routine that most spectators don’t even realize it.
