It depends on your definition of "good coach" than.
If you want to bring up his poor work in 2015, make sure to acknowledge his 13-3 record in 2016, with a team full of rookies. Be fair.
I doubt he'll get another NFL HC job either, but there are plenty of "good" coaches who failed to get a second chance, or whose second chance took a long time.
And again, I agree about the innovation and creativity, that's what I said.
He might not be great or good enough to get this team to the promised land, but he does have some positive attributes just the same. And if he doesn't get them there this year, it won't be an issue for either of us next year.
