Don't get me wrong, I think ND is a solid team. However, at some point you have to actually beat teams with a pulse, not just lose close games.
How good are the teams you beat? That should carry more weight than how good the teams are that you lost to. Even if it is marginally. Give them some credit for close losses, sure. Give them more credit for beating good teams. If you don't have that on your resume, you shouldn't get an abundance of credit for beating terrible teams. Terrible teams aren't playoff contenders, and are a terrible measuring stick of how good you really are.
