Bal ii sheeg taariikhda sida ay NBA u bilaabatay?
Context:Xiriirka Kubadda Koleyga ee Mareykanka waxaa aasaasay 1946 milkiilayaasha garoomada waaweyn ee barafka ee waqooyi-bari iyo bartamaha-galbeed ee Mareykanka iyo Kanada. November 1, 1946, Toronto, Ontario, Canada, Toronto Huskies waxay martigelisay New York Knickerbockers oo ku taal Maple Leaf Gardens, ciyaar ay NBA hadda u tixraacayso inay tahay ciyaartii ugu horreysay ee taariikhda NBA. Goolkii ugu horeeyay waxaa sameeyay Ossie Schectman oo ka tirsan Knickerbockers. In kasta oo ay jireen isku dayo hore oo ku saabsan horyaallada kubbadda koleyga xirfadeed, oo ay ku jiraan American Basketball League (ABL) iyo NBL, BAA waxay ahayd horyaalkii ugu horreeyay ee isku dayay inuu ka ciyaaro garoomo waaweyn oo ku yaal magaalooyinka waaweyn. Intii lagu jiray sanadihii ugu horreeyay, tayada ciyaarta ee BAA si weyn ugama fiicnayn horyaallada tartamaya ama kooxaha madax-bannaan ee hoggaamiya sida Harlem Globetrotters. Tusaale ahaan, finalka ABL ee 1948 Baltimore Bullets wuxuu u dhaqaaqay BAA wuxuuna ku guuleystay horyaalka 1948 horyaalkaas, iyo horyaalkii NBL ee 1948 Minneapolis Lakers ayaa ku guuleystay horyaalka BAA ee 1949. Ka hor xilli ciyaareedkii 1948/49, si kastaba ha noqotee, kooxaha NBL ee Fort Wayne, Indianapolis, Minneapolis, iyo Rochester waxay u boodayeen BAA, taas oo aasaastay BAA inay tahay horyaalka xulashada ardayda jaamacadda ee doonaya inay noqdaan xirfadle.  Bishii Ogosto 3, 1949, kooxaha NBL ee haray - Syracuse, Anderson, Tri-Cities, Sheboygan, Denver, iyo Waterloo - waxay ku biireen BAA. Iyadoo la tixgelinayo midowga iyo si looga fogaado dhibaatooyinka sharciga ah ee suurtagalka ah, magaca horyaalka waxaa loo beddelay Ururka Kubadda Koleyga Qaranka ee hadda jira, in kasta oo horyaalka la midoobay uu sii haystay hay'adda maamusha ee BAA, oo ay ku jiraan Maurice Podoloff oo ah madaxweyne. Ilaa maanta, NBA waxay sheeganeysaa taariikhda BAA inay tahay mid iyaga u gaar ah. Waxay hadda u aragtaa imaatinka kooxaha NBL inay tahay ballaarinta, ma aha isku darka, mana aqoonsana diiwaanada iyo tirakoobka NBL.
Horyaalka waxaa lagu aasaasay Magaalada New York bishii Juun 6, 1946, oo ah Ururka Kubadda Koleyga ee Mareykanka (BAA). Waxay magaceeda u beddeshay Xiriirka Kubadda Koleyga Qaranka 3dii Ogosto, 1949, ka dib markii ay ku midoobeen tartanka Horyaalka Kubadda Koleyga Qaranka.
