I like this. If Rex kept JS we'd be in the playoffs both years, but he was too arrogant for that. Only way to get JS now is with the HC position. He's done really well with less in Philly, including Bills castoffs.
I worry a bit that Lynn may get a HC offer this time around. I'd rather not see the Offense take a step back, but am also unsure what he'd do as the OC for a full year. Right now he's running Roman's playbook, what will/would he do next year? Maybe we'll find out.
Gus Bradley for DC isn't exciting. Jax D was terrible all four years, never improving while Seattle hasn't taken a step back.
Matt Patricia is interesting, but I doubt he'd ever go in the division. He also seems too happy to be winning all of those championships to leave NE.
Dave Toub is also interesting. ST head coaches seem to do all right (e.g. Levy, Harbaugh).
I'd be happy with Tom Coughlin. He's 170-150, 12-7 in playoffs, two Super Bowl wins over the Pats, and 5-2 all time agains Brady and BB.
