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.
