Hache, you bring up some valid points. IMO, there is more than just Tim Duncan separating the two teams. SA has a better overall defense, and has the ability to score more points, and better coaching. This is debatable of course, but I feel that with SA the sum of the parts is better than with NJ.
The reason for my large play on SA is based on the number as much as anything. I have SA winning by 5-7 points almost 65% of the time in this situation. My distributions have been fairly accurate in this series as shown by game.
G1: huge play on the over as I had 192 as very likely to occur, landed on 190.
large play on SA as I had them winning by 8-10 at least 55% of the time, SA won 101-89.
G2: overall loss on SA and the over, smaller plays
G3: overall win on smaller plays
G4: distribution showed NJ winning by EXACTLY 1 or 2 points at least 20% of the time in that situation, large play on weighted middle of SA +2.5 and NJ -1 cashes and pushes, made a mistake of not buying NJ to -.5, medium play on under and prop U 177.5 +230 cash as well.
For game 5 I have SA winning SU over 70% of the time in THIS situation. So with the +1 there was a LOT of value, with the -1 almost as much. Are my numbers ever off? Often. Does what is predicted fail to occur? Daily. Do I ever find value as good as this? Relatively rarely. I was fairly certain when this opened that the # would cross 2, and that had a little effect on the size of the play as well b/c of the middle opp.
As far as the total, when they opened it I figured the # would drop at least 2 points. I liked the opening number under for about 1%, so I put 2% on it hoping to get two numbers in-between after line movement so I could middle 1% back on the over with a fair chance of hitting both.
This doesnt help many people who havent wagered yet, and are stuck with #'s after line movement. I would take SA -2 for 1.5% (If you have to buy off 2.5, I would-I usually buy on/off of 2) and under 179 for .5% or so, the total is a little shaky. Keep in mind that the profit I have made over the playoffs DOES have an effect on the strength of my current plays.
