Does anyone know how to find NFL debut dates? Say Dick Butkus. I look at his page:
https://www.pro-football-reference.c...B/ButkDi00.htm Talks about his drafting,
but no debut, like in baseball-ref. Shows he played in 14 games, so obviously he played in the first game of the season, but this is not the case with everyone. I look at his game logs for 1965 and it shows 5 games, in which he had interceptions, but does not state every game he played in.
