You kinda have to take the option coming for his 5th year. If not, he's as good as gone. Penning had quite a few really bright games. Sure theres room for improvement, but if you let him go your Oline immediately gets worse and now you have 2 gapping holes on your Oline. So now you need to use a draft pick or sign someone else to a lucrative contract in free agency to replace him.
He needs to stay.
