I learned from Chuck Noll in Pittsburgh that speed and explosiveness on defense is the way to build a team. Both are difficult for your opponent to assimilate in practice and then in games it is even harder to match. ↗
Besides Germany, the only countries that don't have speed limits are places like Nepal, where road conditions are so bad that a limit would be beside the point. In other words, it's a little crazy that this is even a topic for debate in Germany. ↗
But to be fair, if you take players from my era to now, the game has changed and the players have many more shots. They use them differently than we did. The speed of the game has changed. ↗
