In the era of making an early commitment, every recruiting class still has a group of prospects who wait until national signing day to commit to a school.
The top quarterbacks are usually pledged to a program by the end of the summer, but the other positions are fair game when it comes to waiting. The advantages of waiting until national signing day are plentiful, as letting the process play out naturally and not forcing a decision will only lead to a recruit making a well-informed choice.
A 5-star running back is going to wait as long as he can, while a talented athlete will take a long look at all of his options. Plus, two SEC schools will be fighting over a defensive tackle all the way to national signing day.
