I agree there's a learning curve, but disagree with where you're directing it
chubba has played in 16 college football games over the course of 4 years.
Haarberg, however, has played in 7 games + 3 series in 2 others over the course of 1 year. he's never received any kind of attention or coaching. he's the one with unrealized potential that everyone should be excited to see stick it out, compete and improve.
he's a winner, he bleeds for Nebraska, he's tough as nails, has the heart of a lion and possesses an iron will. he's unflappable in the face of gigantic headwinds - some certainly of his own creation.
instead, everyone roundly dismisses him and shits on him.
chubba is who he is.
