An assembly including a tubular connector and at least one framing member having a hollow open end and a longitudinally-extending recessed channel. The recessed channel is formed by at least a pair of opposed inwardly-directed walls having inner peripheral surfaces that taper toward one another in a substantially V-shaped configuration. The connector is slidably received within the hollow end of the framing member and has a longitudinally-extending inset track for cooperatively receiving and engaging the tapered inner peripheral surfaces of the channel walls of the framing member. The inset track has outer peripheral surfaces formed by outwardly tapered walls, whereby when the inset track and recessed channel are urged together by a fastener, a slip-resistant joint is formed therebetween. Sports goal assemblies and methods of assembly are also disclosed.
