A volleyball practice system that includes a support frame with a pair of post supports. Each of the post supports being mounted on a base that is supported on wheels, and the pair of post supports being connected to one another by a telescoping or adjustable horizontal member. A backdrop net with a pair of opposite ends along a lower edge that are adapted for tethering to an anchoring point supported by the post supports, so that the opposite ends of the lower edge of the backdrop net may be raised or lowered relative to the upper edge of the backdrop net, so that the backdrop may be used to retain or release balls by adjusting the height of the opposite ends of the backdrop net.

What is claimed is: 1. A volleyball practice system for catching and selectively releasing at least one volleyball, the system comprising: a pair of vertical support posts; a horizontal member of adjustable length, the horizontal member being attached to at least one of the vertical support posts at a fixed orientation relative to the vertical support post to which it is attached; a backdrop net, the backdrop net having an upper edge and a lower edge that is at a backdrop net distance from the upper edge of the backdrop net, the upper edge being supported from the pair of vertical supports, the lower edge of the backdrop net having a pair of opposite ends, each of the opposite ends being tethered to an anchoring point supported by the post supports or a volleyball net lower attachment rope, the anchoring point being below the upper edge of the backdrop net at a distance from the upper edge of the backdrop net that is smaller than the backdrop net distance, so that when the opposite ends of the lower edge of the backdrop net are supported from the vertical support posts they can be moved from a first position where the lower edge of the backdrop net is generally parallel to the upper edge of the backdrop net to a second position where the lower edge of the backdrop net assumes a catenary profile, so that the backdrop net may be used to retain or release balls by adjusting the height of the opposite ends of the backdrop net. 2. A volleyball practice system according to claim 1, wherein said anchoring point comprises cleat. 3. A volleyball practice system according to claim 2 wherein said support posts are mounted on a movable frame having wheels. 4. A volleyball practice system according to claim 1 and further comprising a volleyball net section that is support in a generally parallel fashion and spaced apart from the backdrop net. 5. A volleyball practice system according to claim 4 and wherein said lower edge of said backdrop net is permanently retained in said second position. 6. A portable volleyball practice system for supporting a volleyball net mounted on a pair of posts, the system comprising: a support frame, the support frame including a pair of elongated post supports, each of the elongated post supports being mounted on a base that is supported on wheels, each of the bases being connected to one another by a horizontal member of adjustable length, each of the post supports including: an elongated recess adapted for accepting one of the posts in a generally parallel fashion relative to the post supports; and at least one adjustable retainer that has been adapted for fastening the posts against the recess; and a backdrop net, the backdrop net having an upper edge and a lower edge that is at a distance from the upper edge of the backdrop net, the lower edge of the backdrop net having a pair of opposite ends, each of the opposite ends being adapted for tethering each of the opposite ends to an anchoring point supported by the post supports, so that the opposite ends of the lower edge of the backdrop net may be raised or lowered relative to the upper edge of the backdrop net, so that the backdrop may be used to retain or release balls by adjusting the height of the opposite ends of the backdrop net. 7. A volleyball practice system according to claim 6, wherein each of said post supports comprises an angled section, the angled section incorporating the recess adapted for accepting one of the posts in a generally parallel fashion relative to the post supports. 8. A volleyball practice system according to claim 6 wherein said at least one retainer comprises at least one strap that has been adapted for extending around the posts when the posts are mounted within the post supports, so that the posts are fastened against the post supports with the use straps. 9. A volleyball practice system according to claim 6 wherein each of said bases includes a support rack that are generally aligned with one another when said frame is in a collapsed position, so that the support racks on each base provide a support surface for posts. 10. A volleyball practice system according to claim 6 and further comprising a releasable retainer for engaging a rope connected to one of the opposite ends of the lower edge of the backdrop panel, so that at least one of the opposite ends of the lower edge of the backdrop net may be raised to create a trough below the upper edge of the backdrop net in order to catch and collect balls that strike the backdrop net or the volleyball net section. 11. A method for creating a portable volleyball practice system for supporting a volleyball net mounted on a pair of posts, the method comprising: providing a support frame, the support frame including a pair of elongated post supports, each of the elongated post supports being mounted on a base that is supported on wheels, each of the bases being connected to one another by a horizontal member of adjustable length, each of the post supports including: an elongated recess adapted for accepting one of the posts in a generally parallel fashion relative to the post supports; and at least one adjustable retainer that has been adapted for fastening the posts against the recess; and providing a backdrop net, the backdrop net having an upper edge and a lower edge that is at a distance from the upper edge of the backdrop net, the lower edge of the backdrop net having a pair of opposite ends, each of the opposite ends being adapted for tethering each of the opposite ends to an anchoring point supported by the post supports; and releasably attaching the opposite ends of the lower edge of the backdrop net from the support posts, so that the opposite end of the lower edge may be raised or lowered relative to the upper edge of the backdrop net, so that the backdrop net may be used to retain or release balls by adjusting the height of the opposite ends of the backdrop net. 12. A method according to claim 11 wherein each of said post supports comprises an angled section, the angled section incorporating the recess adapted for accepting one of the posts in a generally parallel fashion relative to the post supports. 13. A method according to claim 11 wherein said at least one retainer comprises at least one strap that has been adapted for extending around the posts when the posts are mounted within the post supports, so that the posts are fastened against the post supports with the use straps. 14. A method according to claim 11 wherein each of said bases includes a support rack that are generally aligned with one another when said frame is in a collapsed position, so that the support racks on each base provide a support surface for posts. 15. A method according to claim 11 and further comprising releasably engaging a rope connected to one of the opposite ends of the lower edge of the backdrop panel to the support posts, so that at least one of the opposite ends of the lower edge of the backdrop net may be raised to create a trough below the upper edge of the backdrop net in order to catch and collect balls that strike the backdrop net or the volleyball net section.
