I never thought of Sutton as a HOFer. He won 20 games only once with very good LA Dodger teams and never struck out more than 209 in a season, striking out 200+ only five times in a long career.
He was good for a long, long time and his career numbers are HOF worthy.
Did you leave “not” out of that last sentence?
I don’t think you should in the hall without some stretch of greatness. Sustained goodness does not cut it for me. That said, obviously the standards of the hall have changed and under the Harold Baines Hall of Fame, Sutton might as well be in.
