Here is the Portsmouth Trojans year by year record from 1913-1919 with highlights:
1913: 0-3.........only season in PHS history without a win
1914: 4-5
1915: 11-5
1916: 16-3
1917: 14-2........PHS advances to "unofficial" state tournament, losing to St.Clairsville
1918: 2-8..........3rd losing season since 1913
1919: 21-1........First season of 20+ wins and only 1 of 4 seasons with 1 loss (1924, 1979, 1988)
1913 was the earliest that I could find an actual record for the basketball Trojans. Portsmouth did field teams before then, but records were unknown. Still, 1913-2013 does cover 101 years of Trojan basketball records.
