Football can be a very unique sport, and one thing that makes it so unique is the simple fact that there are some things that are impossible to plan for. If that were not the case, then every Saturday would be determined by whichever team is the biggest, or the fastest, or has the largest budget.
Some things are intangible, meaning they cannot be accounted for and they cannot be practiced for either. Intangibles are what separate good players from Hall of Fame players, and if someone is going to play Division I football, they likely have something that separates them from everyone else.
