Vice President Biden on Wednesday said he understood from his days playing the sport why the New England Patriots might have preferred to use under-inflated footballs in the AFC Championship game.

The NFL is investigating whether the Patriots deflated the balls to give their team an edge in Sunday’s game.

“Well I tell you what, having been a receiver, I like a softer ball,” Biden said during an interview on CBS News, flashing a grin. “That’s all I can tell you.”

The vice president, who briefly played football at the University of Delaware, added that he “wasn’t bad” on the gridiron.

Both ESPN and The Boston Globe reported Tuesday that an initial NFL investigation found that 11 of the 12 game balls used by the Patriots in their blowout win over the Indianapolis Colts were under-inflated by 2 pounds of air.

Under-inflating the balls can make them easier to throw and catch — especially when it’s raining, as it was on Saturday.

The Patriots, who will play the Seattle Seahawks in the Super Bowl on Feb. 1, could face fines or the loss of draft picks if it's determined the balls were intentionally deflated. In 2007, the team was fined $500,000 when it was discovered that an assistant coach was taping the practices of the New York Jets in violation of team rules.
