Bronx Bombers this season are 0-1 (vs TB) when priced at -200 or higher.
From July 31 2007 through the end of the 2007 season they were 16-5 at -200 or higher.
In the four months before that they were 14-6
Note that a lot of those games were at -250 or higher, so it's not neccesarily a notable profit to play them that high without other cause.
