If you look at Brown and Horn's contracts, expect to pay above what he is likely actually worth. This is the Panthers suckage tax.
Ultimately, much like Derrick Brown, he has steadily improved over time and that's what you want out of your young first round draft picks.
He was one of the biggest and most important question marks coming into the season and he has answered it conclusively. He is "the guy" at LT.
Great news, one less position of extreme importance to have to attempt to remedy.
