Michael Pena Wasted

When I first saw Michael Pena and Emilio Rivera, I wondered why they weren't in the opening credits, but we know why. It got me thinking as I watched the following 5 episodes - I think Pena (and Rivera) would have been so much better off being the follow up crew and not the dead crew. I can easily see Pena deadpanning "dude, you know Tommy will fuck you up if you touch his son, right?" And Rivera has that rep of being a tough guy from Sons of Anarchy and Mayans (but dude is besties with Fluffy Iglesias and is hysterical), both would have been assets to the show.
