Maybe, but Moore was 4th in yards per catch among Brown receivers with at least 20 receptions last season (Jeudy 13.7, Tillman 11.7, and Cooper (CLE only) 10.4). He was even behind one of their tight ends, Jordan Atkins at 9.4. If Moore was going deep he wasn't catching very many of them.
Plus there's still the issue that he's an entitled primadonna like Diggs without the production to justify it.
