This is the first part of a seven-part blog series leading up to Aug. 31, the start of the first official game week.

Topic: The final cumulative completion percentage for LSU quarterbacks Anthony Jennings and Brandon Harris.

Over/Under: 56 percent

Why You Should Pick Over: Haven’t you heard? Brandon Harris has matured mentally and is on pace to win the starting job and have an explosive sophomore season.

The maturing part is what the media has gathered from interviews with coaches and players. They all say Harris is bound to shake off the mental struggles of a true freshman season in the SEC and take hold of the starting job and excel at it. Harris says he’s humbled and physically and mentally stronger (he’s gained about 15 pounds). He completed 55 percent of his passes last season in eight games played with one start.

Anthony Jennings, meanwhile, has another year in the program and says he’s improved his feetwork, which, he indicated, was at the heart of his accuracy issues last year. Jennings completed 48.9 percent of his passes – the lowest of any LSU starter since 2002.

Overall, offensive coordinator Cam Cameron says he’s simplified things for the quarterbacks, something – Cameron admits – he should have done more of last year.

Why You Should Pick Under: Well, the two quarterbacks did combine to complete exactly 50 percent of their passes last season – 136 of 272 – so there’s a pretty good reason to go the under.

Harris’ alleged improvement is tough for the media and public to really see. He’s been allowed to speak once since spring practice, and reporters watched just a portion of the first four days of preseason camp before practice closed.

Meanwhile, Jennings missed six weeks of summer 7-on-7 drills because of a suspension for a June arrest. He admitted last week that the missed time is a disadvantage when it comes to timing with his receivers.

That 56 percent number would have put LSU’s QBs at No. 80-90 in the FBS rankings for completion percentage last season. That’s not good, but it is better than 2014’s 50 percent (well out of the top 100).
