I'm not 100% what you're asking, but my advice is to parse the markup
with lxml instead of html5lib. Here's how html5lib parses the markup
you gave me:

<html>
 <head>
 </head>
 <body>
  <tr">
   <a href="http://rivals.yahoo.com/ncaa/football/recruiting/commitments/2013/wes...">
    West Virginia
   </a>
   NoneOfferedNone
  </tr">
 </body>
</html>

I'm guessing your problem has to do with the fact that html5lib loses
the <th> tag and the <td> tags.

Here's how lxml parses the same markup:

<html>
 <body>
  <tr>
   <th scope="col">
    <a href="http://rivals.yahoo.com/ncaa/football/recruiting/commitments/2013/wes...">
     West Virginia
    </a>
   </th>
   <td>
    None
   </td>
   <td class="offered">
    Offered
   </td>
   <td>
    None
   </td>
   <td>
   </td>
  </tr>
 </body>
</html>

Note that the <th> and <td> tags are preserved.
