Fire Dennis Allen!!

If Allen is still the coach at that time, sure, but a new coach and new outlook would be interesting.

That said, both Peyton and Eli went to the teams that drafted them, so Arch will probably go wherever he's drafted. If the Saints happen to need a QB and can draft him where he should be, then I don't see anything preventing that from happening.
The Colts just brought in one of the most respected GMs in the league, Polian. You forget that Archie forced the Chargers to trade with the Giants. It's not true that they just went to where they were drafted. He made sure his sons were in the ideal situation with string front offices. No way Arch would be here with our current FO/coach.
