If the answer isn't Ken McAuley, then it's almost certainly Gary Laskoski.

- Prior to the NHL, his only experience was at St. Lawrence University, at a time when college hockey was not good preparation for the NHL.
- Went undrafted. Signed with the Kings as a free agent.
- Through a serious of misadventures, he ended up as the Kings' starting goalie for most of 1982-83.
- His career save% (thankfully preserved in compiled game logs
here) was an impressive... wait for it...
.851.
- When the Kings mercifully moved on to other options, Laskoski went down to New Haven of the AHL. He played only a fraction of a season there, with a 4.94 GAA.
- That was it for him as a professional. Age 24, and retired.
This is the only footage of Laskoski that I can find on YouTube... an 8-6 loss.
THAT guy was a starting goalie in the NHL.
