He's being taught and eased in very well. He doesn't need to play every snap just yet. It's the process of learning, making mistakes (if any) and growing. It's all apart of the plan. He's playing tremendous, the best at his position, but the first response to one's mind is he needs to play more.
Anyways, not just because of the JOKer, but if you're 30 years old, welcome to the best Browns football team of your life. Delpit also getting great reviews while in different spots. And no he doesn't need to play more, just learn more.
