Christian Hackenberg is poised to have a big year, but there's been a lot of questions surrounding his offensive line.
The O- line only returns one guy from last year's squad- that's left tackle Donovan Smith.
But there are a few guys who got some game action last season.
All the criticism is just pushing the group to work even harder.
Head coach James Franklin says he has all the faith that these guys will be successful.
"They're working extremely hard, they're working together well. They're a very prideful group. I make the argument everywhere I've ever been that the offensive line are always great guys. They're the best guys. They get very little attention unless things go wrong," Franklin says.
