Think there is a link in the article to the ‘61 freshman team with coach Duncan.
Biden not in the photo or listed on the team.
Also no Biden on any yearbook football team.
I don’t believe the Wikipedia entry is accurate. It gets information from a single article that itself was just a reference to something Biden claimed. Brietbart’s article from two weeks ago was a clear refutation of this, pointing out that Biden himself has admitted he didn’t play college football, and that when he thought about going for the team his junior year, he hadn’t played for 2 years.
It is true that Biden was a decent high school football player, and he probably could have made the delaware team, which wasn’t really all that good.
Inconclusive! When you get down to freshman teams, it can be sketchy. Maybe he quit, or just stopped showing up. I wouldn't press this one too hard.
