Don't count your self out brother, in the age where PRO football players do Pilates, martial arts do translate in areas like balance, agility, limberness, and it helped keep my joints and connective tissue strong.

I still cant figure out how after all those years of football and playing catcher my hips and knees are fine. My shoulders are shot.

In some instanced people that didn't play but learned on their own have a higher football IQ as they have studied the game more than those that have played. Those that played "usually" understand positional concepts, like especially on defense it is not so much as having skilled players as having players that play well together. Explains how Dallas could have big names on their defense and not have a highly regarded defense. The O-Line is another area where team work and synchronization are extremely important.
