A positive way to look at the Carr signing
We are always in a win it all now mode. The Saints are not a NFL team to crash and burn then attempt a four year rebuild.
Also any year, any draft , we can still find the future QB with the IT factor.
Agreed. I am personally not a fan of the idea of 'tanking', and I believe that 99% of the time, no NFL team would do it. The risk of long-term reputation damage, loss of talent and coaching, due to consistent losing, and overall organizational instability, far outweighs the slim possibility that you will snag the next Peyton Manning. It's just bad business. I could go on and on with reasons why it is a terrible idea.
However, something that I don't believe teams do enough, is plan. If you treat each year as a must-win season, and go for broke with FA signings and uncontrolled spending, you give yourself pretty consistently terrible odds of success. There is nothing wrong with managing your payroll, weighing the cost/benefit of each player yearly, and building/maintaining a team through the draft. Take another team from another sport as an example. The Houston Astros never intentionally lost games during the 2013-2014 seasons, but they sucked... Bad. They did have a plan though, which was to utilize their farm system, international FA signings (historically cheap players), and the occasional trade/FA signing. Now they have made it to 6 consecutive Pennants, 2 WS wins, and are firmly at the top of baseball, for almost a decade now, with no signs of stopping.
There is value in taking a measured approach. No team should reasonably think that they will be champs each season, and they shouldn't spend like they intend to. It's just bad business. What we, and all teams, should be doing, is making sure that the contracts we hand out are in line with our long term vision, and that we place a premium on draft picks. We haven't been doing that lately, and it's made this team rely on continuously kicking the can with the salary cap, AND we are still playing subpar football.
TL;DR - No one saying we should tank should be taken seriously, but taking a measured approach, and understanding that you sometimes need to invest in your teams' future would greatly benefit the Saints, and could help fix our salary cap/get us on the road back to success.
Edit: The one caveat generally seems to be a franchise QB. Look at NE under Belichick. A combination of responsible roster/cap moves, and an elite QB allowed them to stay at the top. They are missing one part of that equation, the QB, but they are still able to win a majority of games, and they are still primed to win long term, as soon as they find that QB.
