I thought they were an industry-wide standard, but at CRIS and The Greek I see
25 Montreal Canadiens
26 Boston Bruins
27 Minnesota Wild
28 Colorado Avalanche
at Pinnacle and Betjm I see
27 Montreal Canadiens
28 Boston Bruins
29 Minnesota Wild
30 Colorado Avalanche
Is this just an aberration or do rotnums often vary between sportsbooks?
