Jack Evans began his long professional hockey career in 1948-49 playing three games with the New York Rangers. He also played in three games the following season. It was not until the 1950-51 season that Evans had the opportunity to suit up for 49 games for the Rangers, scoring a single goal.
At the age of 27, Evans was at his prime and got himself into the Rangers' lineup on a full-time basis. For three years in a row, Evans patrolled the defense for 70 games. In 1958-59 he began a new chapter of his NHL career, signing with the Chicago Blackhawks. He remained with the Hawks for five years, winning a Stanley Cup in 1961 with teammates Bobby Hull and Stan Mikita.
At 34, in 1962-62, Evans played his last year in the NHL as a member of the Blackhawks. What is truly amazing is that Evans continued to play professional hockey in the minor leagues for another nine years, retiring with the San Diego Gulls of the WHL after the 1971-72 season at the age of 44.
Evans soon found himself involved in coaching, taking the reins with the Salt Lake Golden Eagles of the ECHL in 1974. He was also named the coach of the year. The following season Evans was promoted to coach the parent Cleveland Barons. In 1978, he returned to coach the Golden Eagles.
As for the NHL, Evans was behind the bench for the Hartford Whalers for almost five years, starting in 1983-84. He put together one Adams Division championship, but that was ruined by a first-round exit from the playoffs. He also had two fourth-place finishes in the Adams and two fifth-place showings, where the Whalers failed to advance to the post-season.
