I have never liked the 1-2-3-4-5 terminology. I still believe the format used in fantasy leagues, is the most accurate. PG-G-SG-GF-SF-F-PF-FC-C . The swing positions are G=PG/SG, GF= SG/SF, F=SF/PF, FC= PF/C Wings would be G-SG-SF-F positions. bigs PF-C. Ball handlers PG-G Some players like Turner can cross extra lines G-SG-GF-SF. Its really all the same, but breaks out each individual ,to one or more positions of use.
