Definitely agree with this.
Because players will still try to return kicks that are returnable, and because some of the worst injuries occur on blocks not involving the returner, a number of coaches wonder if the rule change will achieve its safety objectives. When teams don’t know if a returner is going to call a fair catch or not, there are still collisions on the field. Even on obvious fair catches, there are often collisions upfield.
However, it is clear that injuries are not as severe on plays that result in touchbacks compared to plays with returned kicks. The NCAA rules committee gave this as a key reason it adopted a rule aimed to incentivize touchbacks, and the Ivy League’s two-year research into its experimental rule backs this up as well.
