Kieran Shannon: Over to Ireland to claim three-peat history following Kansas City Chiefs' Super Bowl loss 

There’s a reason that no team has ever won three Super Bowls in a row. And there’s a reason why no one has ever won three Six Nations rugby championships in a row either. It's incredibly difficult.

So one three-peat is denied while another is still on.

Actually, we are being kind to the Kansas City Chiefs to say they were denied on Sunday night. Demolished would be far more appropriate.
