Prefer type of coach? An offensive, A defensive, or a middle guy?

Why are you acting like being a NFL position coach, even for one year, is some sort of huge resume-clincher qualifier over running a ST unit? That’s silly.

You’re arguing a point that seems sort of petty and inconsequential, and treating the title of ST Coordinator as if it makes a coach a total buffoon when it comes to the rest of the game, like they don’t know ball or something.

A good NFL ball coach is a good NFL ball coach. You don’t think Sean Payton can step right in and coach someone’s DB unit? You don’t think Andy Reid could go coach someone’s DL? You don’t think Sean McVay can have someone’s ST unit on-point, including teaching a kicker how to kick?

Just because coaches are known for or specializes in one thing doesn’t mean they don’t know other parts of the game. These men are all football SCHOLARS, including Rizzi, and perhaps more importantly to this topic, are quick-studies in general if they need to learn more finer points about a certain football topic or position.

There are better arguments you can find than this. So if Rizzi coaches a team’s tight ends for one single year, only NOW is he qualified to be a HC in your eyes?

“SMH”
There is a reason why there is not much crossover ( I didn't say none) from offensive to defensive sides of the ball and vice-versa. It's because the league has become specialized. Sure those coaches could coach a p[position on the other side of the ball but they would not be as good as if it were a coach that has experience on that side of the ball.

Once again I guess you missed the part where Harbaugh was a DB and TE coach at major colleges

Would you go to a Orthopedics doctor and have him do open heart surgery? I mean he's a Dr. Right??
