Don't Do This

1: Don't sign a constantly injured, aging, overpriced quarterback when you're installing new offensive and defensive systems and don't expect to contend immediately.  Especially not when you have the second overall pick.  Especially not when it's debatable that he's even any better than the old quarterback you already have on the roster.

2: Assume that because the Titans don't need a quarterback, a quarterback won't wind up being drafted first overall...ok (sigh) the Titans might trade the pick (jeez).

3: Trade maybe the best left tackle in football "just because".

4: Refuse to release a player because he is paid too much.  

5: Refuse to adapt your system to the unique players on your roster, or make your system too complex and inconsistent for young players to get any reps.

6: Get so obsessed with a player that his being cited for expired plates is front page news.

7: Get greedy when trading Manziel to Jerry Jones.  Let him have Johnny so he won't trade up to number one and steal your next quarterback.

8: Priortize arm strength over accuracy, mechanics, anticipation, or football smarts.  

9: Hire Marrone.

Couple notes here: I researched some more on Hue Jackson.  He was fired in Oakland when McKenzie was hired as GM.  Also cited was Oakland's crappy defense, which might even have been worse than the Browns.

This doesn't bother me.  Unlike the Browns defense, that defense really was deficient in talent. A few good players, but a weak secondary and little depth. His defensive coordinator was Chuck Bresnehan.

Jackson had been the Raiders offensive coordinator, so that system didn't require any changes.

If hired by the Browns, key for Jackson will be who he brings in as defensive coordinator. Ideally, he learned from Oakland, and will have his short list. DePodesta could help here.

I would hope he'd be open to retaining DeFilipo as OC, since he did a great job with the passing game, and Jackson is more than qualified to order him to use the best blocking scheme and to run to the right sometimes.

With either of the two guys I've officially recommended to Jimmy (by the way Jimmy you accidentally blocked my texts better fix that), they'll need to focus on their own side of the ball in year one.

For Matt Patricia, Flip would be especially helpful, and Matt would of course mandate the above-mentioned tweaks as well.  This way, there would be continuity on offense, and Patricia would have a good start in fixing the defense.

After the Ryan system, practically any install would seem easy to the players.

Bill Belichick was a great defensive coordinator, and his system is rather sophisticated, which is why he always sought the smartest guys he could get.

But there is continuity from week to week, and certain role-players do the same things consistently.  There is a foundation.

This is why when Bill drafts a defensive player, he gets him on the field quickly.  Often at first he's a specialist, but then his role gradually expands.

The Ryan system is overcomplicated.  In fairness, Rob isn't a clone of Rex, and his own system is more player-freindly and aggressive.

For Hue Jackson, a better-established defensive coordinator might be more important in the first season.  With or without Flip, he will be making bigger changes on offense, and will need a guy he can delegate the defense to.
