Lepper teamed up with Hughitt and Patterson in early 1920 to create the Buffalo All-Americans, then quickly sold the team to Frank McNeil, a somewhat abrasive and aggressive owner who was able to get the team into the National Football League for its first season. However records indicate he may not have actually entered his team into the American Professional Football Association until 1921, the All-Americans are generally shown as the third-place team in league standings from that year (the confusion stems from a statement in the minutes from the league's April 1921 reorganization meeting admitting an unidentified team from Buffalo; this may have instead been the Tonawanda Kardex, who joined the league in 1921, playing only one game). Patterson held on to the Prospects name and put together a lower quality team that played through 1923, including a 1922 game against the All-Americans themselves.
