n.— «It’s worth noting that betting syndicates sometimes try to influence the odds on a primetime game like this one by betting heavily on the favorite.

The technique is known as “steaming”, but books don’t think that’s the case here.» —“Suspicious Seattle betting suspends MNF wagering” by Andrew Folkes Covers.com Nov. 27, 2006.
