During the 3AW call it was not sufficient to use the Riewoldt surname, it needed to be prefaced with either Nick or Jack.
It is a name clarification that is going to be necessary in many future games because Jack looks like joining Nick as one of footy's elite forwards.
While the cousins share the same surname, they are very different athletes.
The AFL Guide lists the 27-year-old Nick at a 193cm tall, and the 21-year-old Jack at 195cm.
On the field Nick looks significantly taller because of the optical illusion created by his longer legs, whereas Jack's height comes from a long body and shorter legs.
In athletic terms, Nick is built like a 400m runner with that long, loping stride that allows him to charge around the Saints' forward half with the rare mix of speed, stamina and marking power.
Forget he suffered a bad hamstring injury early this season. The Saints' captain comeback is complete and he is now back to his pre-injury form and fitness.
Frankly, Jack does not look to have any outstanding athletic gifts except for a quick burst of acceleration on the lead, a big leap and very good balance thanks to a body shape that provides a low centre of gravity.
It would appear that Jack is the typical full-forward, more in the mould of Alastair Lynch or Jason Dunstall, than the Jonathan Brown or Dermott Brereton-like centre half-forward.
His strengths are footy related and more valuable closer to goal where his great judgment, strong hands and quick reactions look like earning him this year's Coleman Medal.
His goalkicking form has been a massive improvement from 2009.
Last Saturday was the first time I have seen the two Riewoldts in the same game. Both Nick and Jack were terrific with 21 marks and 14 shots on goal between them.
In 2004, Nick was the first Riewoldt to be selected in the All-Australian team, and this year cousin Jack should be the second.
