You repeatedly mention that you're capable of taking an objective view at Thompson's body of work but rarely prove that's true.
There's no need for inside information to realize that entering a game with only a single active running back, who additionally was listed as questionable with an ankle injury, is a terrible idea.
It's true that it's difficult to pick up an impact running back during the season although it's not impossible. As an example DuJuan Harris, who wven would have been familiar with the system, was available for several weeks.
Generally it was a mistake entering the season with only two RBs that spent training camp with the team.
Replying to your 4 paragraphs.
1. Will address in the Fire Ted Thompson thread.
2. There is ALWAYS a need for inside info. No one here knows everything that came into play the week of the Cowboys game. The end result of having one questionable RB was clearly less than an optimal result. (the way you word things sounds so much like our current president) Are you a New Yorker?
3. Agree, difficult not impossible. Ever thought about why Harris wasn't signed? All kinds of possibilities there on both sides of the equation.
4. Certainly not normal nor optimal in most cases. Not normal to keep the combination of large number of WR's, CB's, QB's, OL and OLB's that were on our opening day 53 either. Thompson says he likes to keep the best 53. I believe him.
