Let's be realistic. Painter and whoever are not even good backup QB's. Maybe, their reasoning is this. This is probably the first time that the Colts have come to the conclusion that they MUST have someone behind Manning that is going to log some minutes that could mean something. They gave Painter and the other backups a chance to see what they could do. They have concluded that they cannot trust them to hold even a reasonable lead late in a game. So, they decided it would be best to find someone that could come in and at least hold onto a lead and use some clock to maintain a late game lead and run out the clock. This way, if Manning is able to build say a 10 or 17 point lead with 10 or less minutes left in a game, they could put in a servicable backup QB that will be able to hold onto a lead. This way they can shield Manning from further risk in a game that is well in hand and not worry about putting in a backup QB that would be capable of blowing a big lead. Just a thought.
