BR is an asset. He lists his needs. Up to you to follow, fade, or stay away. He is not playing "his" picks and thus has no reason to keep an accurate record. If you want to keep a record, then by all means go right ahead.
On a few occasions, BR has said he likes a side here or there but that's not his style. He has plenty of action from booking the games.
Short term you can get creamed along with the book. Long term will be profitable but remember a book also has vig. Imo, you should use his info along with a few good cappers and along with your read on the game....when those line up, fire the big gun at their azz. Just do not bash or continuously question an asset to the forum. Take his info for what it is.
