Trust me as a Cardinals fan, I know it's difficult to talk about the Matt Leinart saga. My Cardinal compatriots and I would rather never here his name again.
However, I still think there is an opportunity Leinart could be a serviceable backup QB in this league.
To become that solid backup, however, Leinart needs to put in the work. That has always been his problem, and will be until he figures it out.
I believe that once a new CBA is in place, that there are a few teams out there who could possibly take a chance on him.
