Good article man, I know of that sinking feeling, mine was baseball and although I never made it past college ball it was coming to the realization that I would never suit up on an MLB or MiLB field. I am a firm believer in "everything happens for a reason". if i did not walk away when I did I would not have had the opportunities in my current career and would not be where I am today. That being said, if you ever have any rehab questions or need some killer workouts/warmups, let me know!
Thanks man,
