I agree on the 'no lean' technology. If the books set the line to trick people into betting on Team A so that when Team B wins they would take everyone's money, it wouldn't take long for everyone to catch on and bet on Team B. Or any team in any game for that matter. We all know they want equal money on both sides. If it was lopsided enough they would change the number. Since they haven't, it isn't... regardless of what anyone says. The number appears correct (to them), so they move the juice to keep it even. They may claim there is more money on Pats, but just $1 more could always be considered more money on the Pats. They are certainly not going to produce any hard numbers as to how much money they have bet on each side, and since they have no clue as to what will end up happening, they really don't have to care much after they set the number so long as the money is balanced so that they get to keep around half of it.
Bettors have to worry about stats and standings and schedules and yards per this or that, and all that jazz, but books don't, if you really get down to brass tacks.
