How many times do I have to say that backups are not as good as the players they are backing up? There are other players who can pass, run and catch too. They just can't do it at the same level. That's why they would be a backup.
He's not the backup QB. The Saints started two rookies who both struggled without starting Hill at QB when he was healthy.
He doesn't, but he can. No backup is as good as the person they are backing up. This seems to stem from the "I want all pro quality backups at every spot" mentality. It's a Madden/fantasy football pipe dream. No team had all pro offensive or defensive players playing second string offense or defense.
