The NFL approved moving the kickoff line up from the 30 to the 35. Touchbacks occurred on 16 percent of kickoffs last season. In 1993, the last season in which the kickoff was at the 35, there were 27 percent touchbacks. Due to better field conditions and stronger kickers, we're figuring there will be touchbacks on at least 32 percent, and maybe 35 percent of kickoffs under the new rule. Good idea or bad idea?
