It's ultimately TT's responsibility to get it right. he's the GM and President of Football Operations. Period. It's his job to identify whether something is working or not working and find a way to correct it, even if it means making a personnel change. I think it will ultimately prove to have become a bad fit and Capers will pay with his job.

What is the difference between the defenses Capers had in his most successful stops and the ones he's had in the past few years with the Packers? Established veterans and leaders who play well together and get what he's trying to do.

Capers was good when he had established talent, just like some teachers are good at teaching the advanced kids in math, and other teachers are good at working with kids who need a lot of patience, who don't get it right away. Is it possible that Capers is a poor fit for the Packers because he's better when coaching established defensive players and not so much when he's on a team full of players who are young and trying to get established and gel together? Three conditions have to exist for this defense to have success, given how they are currently led and constituted. 1. Capers has to have the ability to teach his scheme to younger players. 2. Those players, by the demands of the team building philosophy, have to be quick studies and be able to assimilate quickly because they will be relied on sooner that many other teams. 3. TT has to knock it out of the park when acquiring talent via the draft. If you look at recent drafts, there have been many question marks on the talent acquired on defense, even when a year of emphasis (I'm looking at you 2012 draft).

Perhaps they hired a calculus teacher who sucks when teaching freshman algebra and the students want to do well, but they really don't get it. Time for Principal Thompson to make a decision.
