It's pretty subjective what a "second line" even is, so it'd be tough to determine. The first team that comes to mind is Montreal from last season. They don't reallty have one superstar (Gallagher being the closest), so they ran basically three second lines of varying talent levels.
Plus throw Byron somewhere in there, who's basically a good middle six winger, and it'd still work.
