There are three reasons Anderson isn't a big name among goalies.
1) He plays for a relatively unpopular unmarketable team.
2) That team has not had any playoff runs with him. He's had two great series performances, but it's not like we've seen him take Ottawa to the conference finals.
3) He's never put up elite numbers in a full season. In 50+ game seasons, he's put up .917, .913, and .911. All his seasons where he puts up elite numbers have been in 15-30 game spans.
If Anderson can remain around .930 while playing a majority of the games this season, it'll significantly raise his profile. Still, without being on a playoff team, he likely won't get the recognition he deserves.
