I might disagree with some of the rules that might be changed in NFL.. but I do believe kick off returns are no longer necessary in the game. It's hard to see a kickoff returned in a game nowadays, players no longer thrive on kick returns. And to the fans, they aren't that exciting to watch anymore. We need to see more real football with more skills in passing, rushing, sacks, forced turn-overs. And besides, kickoff returns cause a lot of injuries that are bad and unneeded.
