Thinking about trying out for my school's football team. What do you know about being a linebacker?
the goal of a linebacker is to provide either an extra run protection or extra pass protection based on the defense play being executed by the team at hand. 
Sounds pretty hard. Are they really strong? I am not a strong man.
well linebackers are memers of the defensive team and line up roughly three to five yards behind the line of scrimmage behind the defensive linemen. you are essentially the backup line, so i imagine they want you to be strong enough. not brock lesner strong but enough to hold your ground
Hmmm. Interesting. Maybe I am cut out for it after all. Who are some famous linebackers?
ray lewis and sam huff. if you are someone who frequently uses judgement on every snap and can think very quickly very well this would be a good position for you. you need to be able to make independent decisions during a particular play.
I've never heard of them. I think I will look at some videos of their play to prepare myself for tryouts.
yes youll also hear of a blitz as in when a linebacker acts as an exra pass rusher running into an exposed gap. good luck with your tryouts!
