A method of training an offensive football player using the device includes positioning an offensive football player being trained on front of the training device, initiating a drill where the offensive football player carries out a conventional football play, and while the offensive football player carries out the conventional football play, moving the training device, relative to the offensive football player, such that the obstacles simulate a defensive rush toward the offensive player, thereby creating a visual and physical barrier to the completion of the conventional football play. ## Claims ### Claim 1 A football training device for replicating a defensive rush, comprising: a base frame; a plurality of obstacles extending upward from the base frame; and a plurality of wheel assemblies, arranged non-linearly, supporting and carrying the full weight of the base frame and the obstacles; wherein in a first use state the base frame is stationary, and in a second state the base frame is in movement over a football field to simulate a defensive rush for a quarterback, kicker, punter, or other offensive football player while executing a drill; and wherein the weight of the base frame and the obstacles is carried and fully supported on the wheel assemblies, without being propped up by a non-wheeled support, such that base frame and obstacles remain upright in both the first state and the second state. ### Claim 2 (depends on 1) The football training device of claim 1, wherein each obstacle includes a mannequin, a support member or frame, and a mount, wherein the support member or frame is connected to the base frame via the mount and wherein the mannequin is carried on the support member or frame. ### Claim 3 (depends on 2) The football training device of claim 2, wherein each mannequin is in the form of a silhouette of a human body. ### Claim 4 (depends on 2) The football training device of claim 2, wherein each mannequin includes a panel of cloth mesh. ### Claim 5 (depends on 4) The football training device of claim 4, wherein each mannequin includes a wire frame on which the panel of cloth mesh is carried. ### Claim 6 (depends on 1) The football training device of claim 1, further comprising a handle, connected to the base frame, for pushing or pulling the base frame, thereby imparting movement to the device. ### Claim 7 (depends on 6) The football training device of claim 6, wherein the handle has a height that is adjustable to provide greater control for a person pushing or pulling the device. ### Claim 8 (depends on 1) The football training device of claim 1, wherein the obstacles resemble the approximate size and shape of human figures representing defensive players rushing the offensive football player. ### Claim 9 (depends on 8) The football training device of claim 8, wherein each obstacle has a height that is adjustable. ### Claim 10 (depends on 1) The football training device of claim 1, wherein the base frame is in the shape of an open-ended “U” or arc as viewed from above. ### Claim 11 (depends on 10) The football training device of claim 10, wherein the “U”-shape of the base frame comprises at least three intersecting line segments formed by interconnecting portions of the base frame. ### Claim 12 (depends on 1) The football training device of claim 1, wherein the plurality of obstacles are arranged in a “U” or arc when viewed from above so as to simulate a defensive rush against the offensive football player. ### Claim 13 (depends on 1) The football training device of claim 1, wherein each obstacle extends upward to an elevation of between five and a half feet and eleven feet above the ground. ### Claim 14 (depends on 1) The football training device of claim 1, wherein the obstacles extend vertically from the base frame. ### Claim 15 A football training device for replicating a defensive rush, comprising: a base frame; at least three obstacles extending upward from the base frame and arranged to partially surround a central area in which a quarterback, kicker, punter, or other offensive football player may move while executing a drill; and one or more wheel assemblies supporting the base frame; wherein the base frame may be pushed or pulled over a football field, thereby moving the central area relative to the offensive player while executing the drill. ### Claim 16 (depends on 15) The football training device of claim 15, wherein each obstacle includes a mannequin, a support member or frame, and a mount, wherein the support member or frame is connected to the base frame via the mount and wherein the mannequin is carried on the support member or frame. ### Claim 17 (depends on 15) The football training device of claim 15, further comprising a handle, connected to the base frame, for pushing or pulling the base frame, thereby imparting movement to the device, the handle having a height that is adjustable to provide greater control for a person pushing or pulling the device. ### Claim 18 (depends on 15) The football training device of claim 15, wherein the obstacles resemble the approximate size and shape of human figures representing defensive players rushing the offensive football player, wherein each obstacle has a height that is adjustable, and wherein each obstacle extends upward to a maximum elevation of between five and a half feet and eleven feet above the ground. ### Claim 19 A football training device for replicating a defensive rush, comprising: a base frame having at least three co-planar segments, each of the three segments being an elongate member, wherein the at least three segments include a central elongate member, a first elongate wing member extending at a non-collinear angle from a first end of the central elongate member, and a second elongate wing member extending at a non-collinear angle from a second end of the central elongate member such that the first and second elongate wing members are separate from each other, such that the distal ends of the first and second wing members are unconnected from other portions of the base frame, and define an open space therebetween such that the base frame is in the shape of an open-ended “U” or arc as viewed from above; a plurality of mannequin obstacles, wherein each mannequin extends upward from a respective segment of the base frame; and at least three wheel assemblies supporting the base frame, the wheel assemblies being spaced apart along the extent of the base frame such that they are in non-linear relationship with one another; wherein the base frame may be pushed or pulled over a football field, thereby moving the central area relative to an offensive player while executing a drill.
