The Bears are in transition. They aren't "tanking". The management is bringing in people with closer playing styles and attitudes they want. That doesn't happen overnight. Claiming a team is tanking implies they are bringing worse people with the express purpose of losing.
The Bears aren't trying to lose, they are bringing in a specific type of attitude and adding talent as they can, with that attitude.
Talent-wise they may be slightly worse than last year, but they are in process of turning around a team and pointing it in the direction they want it to go.
