No way. Hurst is barely serviceable at LT last season. Penning will get better as he continues to get snaps. Literally every rookie LT on his class struggled during the first half of the season and eventually got better. Penning is essentially a rookie and will continue to get better and better with every game under his belt. You don't hinder his development and experience for a minimal gain in the short term. Let him take him lumps early on and get him ready for December, January, and possibly February.
