With all due respect, "value" when it comes to a pointspread are totally impossible to determine. It is all based on opinion, plain and simple. Since even the VERY BEST are only right 4-5% better than a flip of the coin, that surely cannot constitute a big enough advantage in a set of seven games. That small advantage ONLY make a distinct difference over thousands of games, so thinking someone is "good" enough to make a big enough difference over a seven game series is crazy talk (no offence).
Also since only 5 underdogs have lost the game and still covered the spread (one was a push depending on when you bet the game)this year shows, as it usually does, that betting the ML on the dog is also a much "smarter" play than taking the points.
So as usual, betting pointspreads in the NBA (unless you like the fave) is a losing prop. Admittedly I do no bet the NBA that much, but I understand when and where "true value" exists, and it surely is not in mine, nor anyone elses OPINIONS on a game by game basis, especially in a 7 game series when you can get unbeleiveable odds both ways depending on the order in which games are won, and by whom.
The Indy/Bos series, and most certainly the Dal/Hou series offered very nice buy backs. Certainly more than trying to pick a random winner in a specific game, or even each game individually for all seven games. A 6 and 1 record in a series (if it goes 7) is still only paying the guy 4.6 to one @-107.
