The 25-yard line is the key here in determining whether a touchback is good or bad. If the return team was not likely to gain more than 25 yards on a return, for example, then it will be a good thing for them. If they could've gained more than that, then it will be a good thing for the kicking team.

A touchback off a kickoff is almost always considered a good thing. The only time you do not want a touchback on a kickoff is when you are attempting a squib or onside kick. When a touchback happens on a kickoff you know the opposing team will not start anywhere further than the twenty-five yard line.

The purpose of a touchback is to benefit the receiving team by avoiding a possible turnover or negative yardage. It also prevents the kicking team from getting a chance to score or gaining a field position advantage. Touchbacks also help to ensure player safety by preventing unnecessary returns that can result in injuries.

In the NFL, touchbacks serve not only as a rule but also as a strategic safety measure. The league encourages touchbacks during kickoffs to minimize high-speed collisions, which are often associated with a higher risk of injuries, including concussions.
