Either Ing or Craig Billington in 94.
Billington isn't even close.
He was a 15-year NHL player who represented NJ in the 1993 All-Star game. He was an excellent backup goalie who happened to be the guy who started 65 games for one of the worst teams ever in 1993-94, so put up some of the worst single-season stats ever.

There are a few guys from the '80s who would qualify.
However, the guy who is unquestionably the worst starter of the modern era (worse than Ing) is :
Gary Laskoski.
Laskoski was LA's starter in 1982-83.
In 1981-82, Laskoski was the backup for St. Lawrence University in the NCAA. Appeared in 15 games, went 7-7 for a team that was 12-4-1 with the other goalie in net.
Undrafted, he only signed a pro contract with the Kings on October 22/82 (a month into the 1982-83 season) having never played a game in the minors.
Somehow, he stepped into a vacuum in the LA net (after the career of Mario Lessard had gone into a tailspin), and appeared in 46 games in 1982-83, posting a miserable 4.56 GAA and .857 save %.
In 1983-84, Laskoski quickly lost his job in LA after posting a 4.96 GAA and .829 save % in 13 appearances.
Sent to the minors, Laskoski posted a 4.94 GAA and .857 save % in the AHL over 27 games for the rest of the season. He went 7-12 on not a bad AHL team that was well over .500 with Markus Mattson/Mike Blake/Darren Eliot in net.
Following that season, he retired and never played another game of pro hockey.
So in the stretch from 1982-84, Laskoski went from an undrafted college backup with few hopes of an NHL career to an NHL starter to an AHL sieve to retried.
Worst ever, easily.
