Nobody should expect that. But size doesn't equal success. He's bigger than Covey. Shoot, he's also bigger than Jaylen Dixon and Demari Simkins too. They're all speedy guys and have had success in college. Quick, speedy guys spend their days developing a knack for getting open that doesn't require muscling someone around. BYU has passed the ball successfully, both short and deep, to smaller guys for a long time.
But I agree that it's too early to start talking about him doing a ton. However, he has the potential to be successful, and he's not "too small" to accomplish anything.
