The Giants have no reason to even consider Leinart for their roster. Personally, I would rather have Rhett Bomar remain the backup than bring in this guy. In fact, Bomar is a better player right now than Leinart is.
Leinart is a turnover machine who is just days away from a visit from the Turk. The Cardinals probably plan on cutting him Saturday. They have Derek Anderson and John Skelton, who are both muuuuuch better prospects. That is why they are dangling Leinart out there right now, hoping some sucker will make a deal for him.
Jerry Reese is smarter than that. As Paul Schwartz of the Post tweeted this morning ..."Matt Leinart to Giants? Forget it. Not gonna happen. "Discussions" were probably Cardinals calling Giants and Giants saying "No thanks."
