grow up lol...anyways...lets address some things here
First shawn, no, your wrong. I played high school football all four years and that just might be the most ridiculous thing you've ever said not to mention the fact you are comparing high school position selection to professional sports recruitment

.
Second, if there's a weakpoint in an offensive line defensive coordinators pick it up in about ohhhh .02 seconds (because thats their job!) and overload or blitz that side to exploit the weakest link. How can you assume a HB/TB is going to pick up the slack a poor offensive lineman creates? Maybe if a formation calls for it like the I, Proset. But what about shotgun formations with no back at all? There's just too many situations and formations where O-linemen can't rely on the rest of the line or runningbacks to compensate for their poor play. If there is one weak man on that line he's gonna get ran over, around, blitz at, all day long. The team won't perform well because they've lost the running game to that side, have more pressure coming from that side, and have to make up for that single man's poor play by sacrificing another offensive lineman to help double team. Teams with bad offensive linemen simply don't have the offensive production that teams with good Olines have. Furthermore, how can you say a QB has no one to help him out?! Offensive coordinators call all the plays, accept for audible siutations, the O line BLOCKS for him as well as the runningbacks in certain cases, and wide recievers CATCH the balls he throws! What the hell are you talking about! he gets the most help out of anyone on the field!!!! lmao!
