What are the chances that todays game is more about coaching?

Harbaugh or Tomlin never won off teams they built. Thats the key difference. Both won off Brian Billick and Cower who both set in the booth now. If Brian Billick ever got back into coaching, it be a sight to see.
I hope you realize that Ray Lewis was the only player left from the first Ravens Super Bowl, when Hardbaugh won🤣🤣🤣
How was that not a team that Hardbaugh built?
