Just seeing a list means little. Yes, scouts watch games all the time. Does that scouts' team play one of the teams in the near future? Was he in that location for another game? For a regional meeting? Maybe watching a junior game? Are there pending free agents on either team? Lots of factors.Wouldn't you expect scouts from several teams at any given NHL game? It is the job of pro scouts to scout pro games, isn't it? I'm not being a smart ass. I don't really know how it works.
It is more interesting when scouts show up in a location away from the major hubs to watch a team they are not playing for a long while (or have finished playing them for the season).
