bk, I think the opposite is true, ESPECIALLY if you have a following For example, if RAS releases a game OVER 140, and it closes 136, it would be ez to say "SURELY, this is a great play now".
The truth is that it probably is a rare total lemon......the ONLY way this line collapsed is for someones to be betting a TON of money THE OTHER WAY, not just moving the line, but offsetting the RAS bettors........
This phenomena explains why if RAS releases and you wait an hour, and then only bet the plays where you get the release numbers, you likely will get your teeth kicked in........DESPITE RAS hitting 56%
