Named Range - Data Validation List

I have a named range that includes columns A, B, C, and D - Called QB. The name of the tab which the data lives on is also called QB.

In another sheet, I have a data validation list in a column titled "Position" with the following entries: QB, RB, WR, K, DST, TE.

Next to the Position column is the Player column. When the user selects a position from the drop down list, the Player column is populated with a data validation list of all the players from the selected position (the data validation used INDIRECT to populate the list).

I want to use VLOOKUPs to populate other columns such as Bye, Salary, and Team based on the named ranges (which I know how to do).

The problem is, how do I limit the lookup of the "Player" so that the player validation list does not list all of the columns in the named range?
