The point spread for Sunday’s Jets-Patriots game has suffered a little shrinkage as kickoff approaches. New England is favored by 21 ¹/₂ points at William Hill sportsbooks, down from a mid-week high of 23 ¹/₂.

Nick Bogdanovich, director of trading for William Hill, said sharp (professional) bettors “jumped on the Jets” at +22 late on Friday, prompting the tick downward. Bogdanovich says though there are plenty of public bettors wagering on the Patriots, many sportsbooks are offering them at -21.

According to The Gold Sheet handicapping resource, just four teams favored by 20 points or more have lost the game outright since 1957. Interestingly, the Jets accounted for two of those, both in their 1968 championship season — as Joe Namath threw five interceptions apiece in losses to the Broncos (+22) and Bills (+20).
