ABSTRACT:
A ground support structure and a base system are provided in which the ground support structure is configured to have a recessed area disposed inside a peripheral rim, into which a base or a drag plate may be inserted and fastened. The associated base has a principal lower surface and a ground support-engaging lower protrusion that has a fastener corresponding to at least one fastener on an athletic device mounting surface disposed in the recess of the ground support structure. The drag plate is configured to substantially fill the entire area of the recess, and to provide an upper planar surface that is essentially flush with the peripheral rim on the ground support structure.
