National signing day can be one of the most exciting days of the year for a college football program. Conversely, it can also be a very disappointing day.
The line between commitments and decommitments is often very thin. The choice between one hat or the other can sometimes come down to a last-minute decision or last-second recruiting push.
Victory and defeat are oftentimes separated by inches on the football field, and the same can be said on the recruiting trail—but instead of inches, it comes down to moments and sometimes even seconds.
One second, you think you have an elite recruit locked up. The next, you hear that he's gone to your rival. Sometimes it's the other way around, though, so you really never do know.
That's the drama of national signing day, folks.
