OTAs Week 1’s Practice Notes & Highlights: Trevor Penning moving to Right Tackle

DA and Benton aren’t calling their reps cross-training. Their statements in their post practice pressers shows that they plan on further exclusively installing Fuaga at LT and Penning at RT going forward. Benton sees Penning as a Right Tackle in this scheme. They can’t afford to put Fuaga and especially Penning through any experiments. They have to fully learn where they’re going to start.
In theory cross training seems like a great idea. Nobody is going to argue that versatility isn't a good thing, but sometimes it's better to let guys focus on one thing and get a firm grasp on it. So in this case we have a rookie and a third year player who struggled at LT. Let them focus on where they are projected to play and give them as many reps as you can so they can learn that position.
