Not much, according to Tiki Barber:

Tiki Barber, who fell out of favor with the Giants when he criticized Tom Coughlin and Eli Manning after his retirement, talked himself into more controversy this week, when he compared himself to Holocaust victim Anne Frank.
In a Sports Illustrated article, Barber, the former Giant who is attempting a comeback to the NFL this season, talked about moving with his girlfriend Traci Johnson into the house of his agent, Mark Lepselter. He said they were hiding out in his attic.
“Lep’s Jewish,” says Barber, “and it was like a reverse Anne Frank thing.”
Barber last played for the Giants in the 2006 season, the year before they won the Super Bowl, and landed at NBC, where he made headlines with sharp jabs at Coughlin and Manning.
