<xsl:if test="@team=ALL">
    <td class="th"> Team </td>
</xsl:if>

Your XPath is interpreted as: value of team attribute = text value of all child elements of current node with tag name "ALL", which would always be false for your example.  What you apparently wanted
was:

<xsl:if test="@team='ALL'">
    <td class="th"> Team </td>
</xsl:if>
