Nevadaref BillyMac wroteBack when I was playing in the 60's, the 1960's, not the 1860's, I remember "force outs". I can't remember if "force outs" were called in pickup games in the driveway, or in organized games with officials. Was there ever such a rule, or is this just one of those urban myths? Nevadaref wroteThe NBA definitely had a force out rule. I'm not sure about HS. I'll consult the NFHS handbook. Found it. According to the NFHS Basketball Handbook the "force-out" provision was eliminated in 1963.
