Puck Line

A couple years ago I asked about reverse run lines in baseball.  Similar situation here with hockey.  It has taken me a while in scoping out hockey lines to see that sites like covers.com seem to use ambiguous (some would say wrong) language.  They tell me what percentage of the public is taking a side.  Fine.  What’s not fine is that they ultimately list these picks as ATS.  But these are money line picks.  Unless I am off-base, sites like covers and thespread run contests where people enter in ML picks and the site turns around and displays these as betting trends.  Obvious flaws if this is the actual system are that these picks are not being made based on actual wagers and the puck line is not even a consideration.  I want to know

1) if my claims about these sites are correct

2) if there are sites that give actual betting numbers for the money line

3) if there are sites that give actual betting numbers for the puck line

4) what love is
