The Ravens are 2-0 thus far in games in which coach John Harbaugh wears a gray, team-issued T-shirt. Harbaugh wore the T-shirt in wins against the Cleveland Browns on Sept. 18 and the Jacksonville Jaguars on Sunday.
Harbaugh said the T-shirt endured humid and sweaty conditions in Jacksonville before assistant equipment manager Tommy Wood reclaimed it.
"You know, the T-shirt took a beating yesterday," Harbaugh recalled Monday. "It was hot, kind of rough, a lot of hugs happened out there, but he said, 'We're saving this one.' So it'll be laundered up and ready to go next week, I guess."
But there is apparently a shelf life for the T-shirt. Asked if fans will continue to see Harbaugh wear the T-shirt when the Ravens visit the New England Patriots on Dec. 12, Harbaugh replied, "You will not. I don't like being cold."
What about if the team continues winning games in which he wears the shirt?
"If that T-shirt can stretch and fit over a parka or something like that, then we might have a chance," Harbaugh said with a laugh.
Harbaugh said a link between his attire and the Ravens' ability to win games does not concern him.
"I'm superstitious about not being superstitious," he said. "It's really important not to be superstitious."
