What would Betts get on the open market today?

[ArtMonkDrillz]

I saw this in an NFL.com mock draft article and thought it was kind of interesting...

8. Houston: Adrian Peterson, RB, Oklahoma -- There is still a chance the Texans trade for a running back -- maybe a Ladell Betts -- but if they don't, Peterson is the class of the running backs in the draft. If Houston trades for a runner or signs one in free agency, then Penn State tackle Levi Brown is a smart choice.

What would we ask for in return?

*I don't know if this was written before or after the Texans got Green.
