Do it! You'll have memories for the rest of your life.
Leg strength and cardio endurance ... Your frame sounds like a wide receiver . You need speed, agility, and GOOD hands... A nice jump won't hurt either
Football is just as physical as it is mental... Knowing you can do something goes a long way to actually getting it done
Keep us up to date on how the games go and don't EVER quit. No matter what. Hit the weight room every day that you're allowed and pay attention in practice
That's my experiences
