I don't think McNair "knows" football.
I think he enjoys the pageantry surrounding it, and certainly the $$$.
But the in-depth ins and outs? He doesn't have it. And his GM is (drum roll please...) a FOK'er. Friend of Kubiak.
JJ Watt has maybe actually set this team BACK because without him, we would have cratered. There is no bigger fan of Watt than Smithiak.
