UPDATE: The add onto my previous post... I think the linked checklist is correct and based on these cards from COMC [1]. The linked checklist is based on Beckett [2]. However, COMC has the posted Reggie Bush card as "Top Picks" [3], which comes with a mixture of cards including one already present in the checklist (#7). Perhaps someone else can shed more light because there is a mixture of promos for 2006 SAGE related cards for players such as Bush, Young, Leinart, etc

COMC has the #1 Mario Williams from the linked checklist listed under a different set (2006 SAGE Aspire) and subset, which they actually do not even name [1]. Therefore, it looks like that subset needs to be created once we can identify all 10 cards [2]. After that, the Mario Williams images moved, and the current instance replaced with Reggie Bush.
