People trying to compare Williams with other 'dual' national players, are really getting confused.

Some of these players have come through the Welsh schoolboy and junior section, and nearly all have one Welsh parent.

If you want a fair comparison, then compare Williams with Ryan Shawcross and Ben Turner. Both have the same eligibility as him, i.e one grandparent, but both politely declined as they were more English, and didn't want to deprive Welsh players of caps.

The fact that Williams accepted tells you all you need to know about the guy, and his ego.
