Does anyone actually believe there's a coach that knows more about special teams than DeCamillis, or any other ST coach out there? It's about roster depth, not coaching. If you have fast, good backups, you can run down the field and make a tackle. If you have a great returner, you have a great return game. If you have a great kicker, you make a lot of field goals. If you have a great punter.....etc. Changing the special teams guy changes nothing. Talent does.
