This is one thing fans never understand. The minute a team goes 3-4 games under .500, they want the team to tank so they get a high draft pick. Teams don't think like that because they are businesses and you cannot run a business that way. Heck, even good athletes don't think that way. However, fans are the vocal majority and they tend to freak out the moment anything goes wrong.
Look no further than the Game Day Threads when the other team goes up by 7 or 10 points. A lot of fans give up and start wanting players cut, coaches fired and wondering aloud who we can draft next to fix the guilty player of the moment. As fans, that is our right, but if you run a sports team, especially an NFL team, you cannot think like that if you want to continue generating money that allows you to pay for those free agents you believe will solve all of your problems.
The reason they rushed Romo back early last year was because the team kept losing without him. If the team was winning 40-50%, or even 30%, of the games without Romo, they could have and likely would have let him take more time to recover.
As good as this team has been this year, there have been several plays near the end of games that if they did not happen could have vastly changed the outcomes of those games. Just because things seem great now does not mean things cannot change. Injuries can happen, off-the field issues can happen, players can get suspended, etc.
Fans are fickle and impulsive, which again, is our right as fans. We have nothing but our emotions invested in our favorite sports teams. Team owners, coaches and players have a lot of money invested in and affected by the operation and success of the team and they have to make decisions based on that. When it works out, we praise them and say, "Executive of the Year!", "Coach of the Year!", "Rookie of the Year!", "MVP!", etc. When it fails to work, we say, "Mistake!" and "I knew it!" along with "Retire!", "Fire!", "Trade!", "Bench!", "Cut!", etc.
Between the Madden and now Fantasy Sports generations, people think solutions are simple and if you are in the lead, you are a genius and if you are not in the lead, you might as well give up.
