Jordon Hudson's in her football-lovin' era ... 'cause she wore a Taylor Swift sweater to the University of North Carolina's game to cheer on Bill Belichick.
The head coach's better half walked the sideline before UNC's matchup against the Univeristy of Richmond Saturday ... shaking hands with several men while standing alongside Bill.
Her sweater -- featuring a large tiger face on the front with the words "Blind For Love" written underneath it -- is perfect for any Swifite ... 'cause it's exactly like the one Swift wore in the "Look What You Made Me Do" music video.
