Future O-line and Helmuth

It seems clear at this point that our offense cannot succeed as long as our O-line continues to play as bad as it has. So what do you think we can expect of the future? Are we doomed to more years of similar play? Or are the guys like Oneal and Mealer going to be enough to secure our line and give McGuffie the opportunity to break through to the secondary (or at lease the line of scrimmage).

Also whats with Helmuth. Hes now a sophomore and has gotten almost no playing time. He was recruited a the top fb in the nation and was known as a devastating power runner. Granted Moundros might be our best run blocker at this point, why is helmuth not seeing any carries. I know that rodriguez utilized his fb's in WV. Doesnt helmuth seem like a better option to run the ball at fullback than grady.
