Without question the offensive/defensive lines are a huge part of their success and I'm not sure they ever receive enough credit, this season and past seasons included. Not a bad call on the MVP either, Hewitt certainly doesn't get the stats but it shouldn't be understated how important he is to the team. As you mentioned, he's used in a few different positions and can do a lot of different things for them. If he's not the most valuable he's certainly in the conversation
