Former Jacksonville Jaguars offensive coordinator Jedd Fisch was fired just days following the 2014 NFL season. There were a lot of reasons given: "philosophy", "seeing eye-to-eye", and "on the same page" were some of the more common phrases uttered by head coach Gus Bradley.
Honestly, he just wasn't good enough.
Fisch can put together an offensive game plan for a college program. He did well at Miami and he'll probably do well at Michigan. That's his ceiling. But it doesn't mean he didn't have a few very well-designed plays that succeeded for the Jaguars last year.
