3-4 Adjsutments for Vitt?

While coaching in the NFL for this long would be beneficiary, it doesn't necessarily imply how good of a coach one is.
I'm sure you can pull up a list of coaches currently in the league with 30+ years of experience and find some that are washed up.

It's hard to tell what kind of coach Vitt is solely based off his LB's performance. If Scott Shanle misses a tackle is it Vitt's fault?
Not saying Vitt is or isn't a good coach, just playing with some logic.

I hope we pair Rob Ryan up with a fresh defensive mind out of college to coach the LB's. We need to rinse ourselves of last year's stank and keeping Vitt, a 4-3 guy, to coach the guys on the 3-4 front doesn't sound like the best idea.
Put Vitt as assistant HC/motivational speaker lol

But usually if you've coached that long, particularly as a position coach, you know scheme/technique pretty well. What specifically are we implying that Joe Vitt won't understand???

I don't know why we act like the 3-4 is some kind of novelty or newfound revolution in the NFL. It's been around for a while. Defense isn't like offense. Knowing the 3-4 is not the same as understanding the intricacies of teaching the West Coast Offense.

Defense is defense. Linebacker is linebacker.

Also, we're really overly focusing on the switch from the 4-3 to the 3-4. I'll bring up, again, that GW ran plenty of 3-4. Moreover, he and Rob Ryan come from THE SAME COACHING TREE. If anything, Vitt spending 3 years under GW is going to have him familiarized with the terminology and philosophy of Rob Ryan's defense.

If we're trying to be coach evaluators here, I have no desire to participate in that conversation because it all comes down to opinions and what kind of mood each poster is in. If the question is whether or not Joe Vitt has had enough exposure to the 3-4 in general or Rob Ryan's version of the 3-4 to contribute as a coach, the answer is a very very very confident YES.
