I don't think "is it exciting?" should really be the ultimate arbiter of decisions made by the NFL, "is it good for the game?" being a better one. Certainly, excitement is good for the game but the game would be plenty exciting if we took special teams out of it entirely, and the excitement from the rare big kickoff return is more than cancelled out by the all-too-common injury on a kickoff situation. Plus, it's not like the league passed a rule outlawing Devin Hester (unfortunately)... it's not like teams don't have to punt anymore.
