That is an entirely different discussion. We are talking about lines, value, and at what price are you wiling to take for a play.
Best team means......the better team overall or the better bet for that game?
Go back and look at lines and outcomes and tell you who's winning? Its a mixed bag of favorites and dogs of all prices. Not sure what you mean here.
I'll give you an example.
If I have a situation where a dog wins at a 50% clip, then I will take that dog at any price. If I have a situation that is profitable if the dog is a big enough price, for example dogs of +130 or higher, then the price absolutely determines if its a play or pass. I'm passing at +115 and I'm playing at anything over +130. Same thing applies to point spread sports. There are some situations where the spread absolutely dictates whether or not I play or pass.
Your comment that point spreads mean nothing in football and hoops is a complete head scratcher.
"always forget about the line, winners don't need the points, TD's, hoops, whatever."
