Quarterback Tom Brady and his wife, Gisele Bundchen, were spotted heading in and out of a Patriots team Halloween party on Monday night. Bundchen confirmed their Oz-inspired costumes on Tuesday morning when she posted an Instagram picture of the two of them all dressed up as Dorothy and the Cowardly Lion. As for Brady’s coach, he apparently is capable of smiling, as this Halloween photo (at right) that Bill Belichick’s girlfriend Linda Holliday posted on Instagram shows. “Ok ok,” she wrote, “I’ll go get that beer for you!! #piratepranks#Halloweenfun Love this handsome Pirate!” . . . Patriots tight end Rob Gronkowski and his family seem to like cartoons. According to Deadspin.com, the family is pitching an animated series, tentatively titled “The Gronks,” that would tell their sports-family stories.
