I will give you a straightforward analogy to answer this question. Lets say you really wanted to attend an event, be it your favorite bands concert, a big rally, a championship game, etc, and somehow scored last minute tickets. But unfortunately the event was across the country, and when you looked up last minute flights, they were all outside your price range. If you live in Seattle, and the event is in Miami, would it make sense to spend all the money you do have to buy plane tickets that get you to Chicago at the same time the event starts in Miami?

You couldn't get tickets to Miami? What should you have done, sell a kidney to afford the last minute flight to Miami? Turn a trick at the park? So you buy the ticket to Chicago instead because you got the best you could get with the resources you had a the time.

But the thing is, the event ain't in Chicago. Half way there is not there. When you land in Chicago at the time the concert starts in Miami, you guarantee missing the concert, and have flushed your entire bank account down the toilet to watch it rain in a place with different trees, and now you have less money in the future to buy tickets and travel to any future concert.

This is what the Saint's did with Carr, they settled for the guy who could only get them half way there. In theory, the Saints want to go to the Super Bowl, except for Guido who I believe said championships are not the goal and just wants to go 9-8 every year to save face and have rank as some sort of beta king of the NFC south. Carr will never get the Saints to the Super Bowl, even if he is better than the worst option. Neither will Dennis Allen. They are a ticket half way to the destination, but can't go all the way.

So what should you do if Carr is the best option you can afford? You should pick a worse option that costs less and save money so you can afford a better option later that is actually good enough to go all the way. Just like this person wanting to attend a concert in Miami should not buy a flight to Chicago, they should save their money, scalp the ticket, and save up until they have enough money to get a ticket and travel ALL THE WAY to their destination. This is called rebuilding. Its better than building for 9-8 every year with no patience, and sometimes when you take risks instead of the safe 9-8 known commodity you hit the jackpot earlier than expected so losing in a rebuild is no guarantee, while putting off a rebuild is a guarantee to never win.

Also, Arthur Blank's answer is that he would sell a kidney, turn a trick in the park, buy a ticket to Chicago, and buy a standby ticket to Miami. At least we didnt do that. He might get to Miami but it won't do him a lot of good if he can't sit down and he can't stand up.
