Hi, I am a linebacker in football! 
Really? So you are a member of the defensive team?
That is correct! It is a tough job as I have to defend the football from the other team.
So your goal is to provide either extra run protection or extra pass protection for you team, right? Must be hard work. 
Yes! It is pretty hard due to the fact I get tackled a lot. I try my best though! 
Do you blitz a lot? Which occurs when a linebacker acts as an extra pass rusher running into any exposed gap.
I do quite a bit when we are losing the game. A blitz is a good idea to hopefully catch up in points!
I agree, thats why Linebackers are often regarded as the most important position in defense!
