I'm not worried about any of the drops on this team. They are fixable. Everyone on this team is a hands catcher with good technique. DJ's problems are having his hands ready when he breaks. I could fix this yesterday. It's just brining your hands up like you're going to block then cut hard to the pass route, and hands are chest height to receive the quick balls to his core.
Claypools are contested catches and will involve a little more bulking up and hand strength. Think of early JuJu, he transformed his body this year, and is a bear out there in routes. Claypool is a rookie, so hand strength and filling out his frame will be a big move this offseason, but they both have all of th skills to be a AB/Bryant combo.
