Being a strong performer on the football field has many attributes that transfer well into whatever career most interests you. Focus, discipline, and relentless execution were the key areas that I emphasized when I coached youth football. Those areas apply beyond the football field as well. Leadership, dedication, and driving toward achieving goals are other attributes that transfer well from sports to your ultimate career. Start thinking about what you are passionate about and begin to explore potential opportunities in that space. When you enjoy what you do, you will do it well and it won't feel like "work".
I encourage you to do some on-line assessments to identify additional strengths. You want to have several career paths open to you based on a variety of strengths. One additional strength I can see right away is probably team-work. Some people prefer to work alone, rather than with a group. You likely have other attributes, such as physical stamina, hard work, dedication (showing up for practice), and things like that. Ability to plan and execute plays makes you analytical, as well as quick-thinking, flexible/adaptable. These are all things that transfer easily into the business world.
I am not trying to discourage you from sports. It's not something I know a whole lot about. I just wanted to show you what we call "transferable skills." That is how skills in one area can be used to land a job in another area, even one that is seemingly unrelated.
