Nothing about Tanner McEvoy's career has been conventional. Why should that change now?
Potential is a funny thing.
Oddly enough, it's usually used as a part of a positive connotation. If you have potential, you have promise. It's a good thing. Some people have achieved great fame and success on potential. Others have lost money and their jobs based off of other people's potential.
Webster's defines potential as "capable of becoming real." So that's the thing; those who have potential have not achieved what they, in theory, should be able to achieve. Maybe it's because they simply aren't there yet, or maybe they'll never reach it.
