Just my 2 cents, but I think he’s likely slightly behind in learning the system. It’s one thing if BK and CO were scrubs. You have at worst, two average QBs who understand the system vs a QB that can make every throw in the book but is still trying to fully understand the system and execute at game speed. He could be lighting the world on fire and making tight window throws, but if Gilbert has to limit his playbook, is that worth it? If not, now you’re back to square one choosing between BK & CO.
