Some quotes from the article:

Unfortunately he's also legendary for speaking impulsively and leaving others to clean up the mess. "He lacks the filter," says one Democratic strategist. Or as a senior Senate foreign policy aide put it: "Biden is an unguided missile." Not exactly the persona you want out front when the country is at war.

He gives Castro-length speeches," says one exasperated Senate staffer. In Democratic caucus meetings, he is famous for declaring, "I'll be brief," and then talking the room into a stupor. (Biden's colleagues have been known to burst into laughter when he makes that promise.) People who know Biden also warn that his loose talk often reflects muddled thinking. In his classic study of the 1988 presidential candidates, What It Takes, Richard Ben Cramer wrote, "Joe often didn't know what he thought until he had to say it."

Still, some Democrats worry that Biden's flapping tongue could cause p.r. problems down the road. "There probably should be some small concern," says the Democratic strategist. Any wrongheaded declaration by Biden "would not be deliberate; it would not be that he stopped being a team player and decided to go out and conduct foreign policy on his own. It would be just that he was out there and talking."
