First and foremost, I never stated that Jensen would be an upgrade. They're your words! I used his name only because he "is" the backup center as listed on the depth chart.
To be honest, I could care less who they would decide to use. The important factor is they need to make an effort to fix the problem. Obviously, they have enough tape on Zuttah to know he is not the answer considering he hasn't made any progression in rectifying his issues to this point.
There is certainty that they can't "upgrade" the position unless they try someone else, in real game situations, since game situations is all they have left.
I agree that they see 100% of the things I/we don't see and i'm sure they didn't foresee his veteran play dropping off as much as it has. But, if he is our best/only option to continue, we are in big, big trouble.
Look man, I only want our players to play well, win more and remain healthy. Nothing more, nothing less. If my fandom offends you, that's your problem, not mine.
