Why is Joe Banner’s coaching future so uncertain?

When Joe Banner was hired by the Jacksonville Jaguars, he said he wanted to win championships, and he was willing to do whatever it took to do it.

The NFL did not see that.

Banner’s tenure with the Jaguars was short-lived, but he did build a foundation for the future of the league.

So why is it so uncertain if Banner is going to return to the coaching profession?

It’s not the first time that the Jaguars have made a coaching change, and there’s no reason to think that they’ll make it more likely that the 49ers are looking at a replacement.
