Its easy, everyone does it. Seriously, dont worry. Your not the first and your definately not the last to over look the play of the offensive line.
    Almost no one follows the play of the o-line not from the youngest fan, to the great Gene Deckerhoff, even the running backs dont pay attention. Next time you watch a football game try and count how many times a running doesnt follow his blockers and is punished for it. Offensive lineman are used to this though, and it starts the first season they play that position.
    Its Friday, and 6 AM and i trudge out of bed, but i have to be in the whieght room by 6:45 so i can lift for an hour and a half before school, its the fourth time this week, wendsay being the only off-day, on wendsay the backs and recievers lift for thirty minutes and then run routes. Things like this are mandatory though for me and my fellow offensive lineman, because you have to be the strongest player on the field at all times. dont think so. Well think about it, what does a blitzing linebacker mean to an offensive lineman. It means that someone is gonna run as fast as they can at you from about five yards away and try and nock you over with all they have. its a scary feeling.
    usually during football season between game practices are typically light (shorts and shoulder pads) but not for lineman who are still going full contact. Why? because the offensice and defensive line is the only position the is guranteed to have hitting on every play.

     There are times when it becomes very frustrating. Most recently at my schools spring game, i was plaing left guard, mid-way through the 3 quater i saw that the outside linebacker was blitzing, i pulled outside and nocked down the backer and the qb got the pass off. did anyone notice...Yes Davis bass the line coach.

also, you hear all those storys of football players going on seafood diets (see food eat it),
not for the olineman.Most offensive lineman are put on strict diets to control there size.

so next time you watch a game, just be more cognisant of the play of the offensive line, because they are working hard to make other people look good.

I still wouldnt play anywhere else.
