Maybe, but shrinking his arsenal is one thing....more than doubling the usage of a demonstrably s***** pitch is another.
I'm more of the belief that the organization really loves that pitch amd if you tell them you throw one...its gonna get abused until it works ...even if it never does. It's not a pitch with great velo separation from his fastball, it doesnt have great movement... so using it nearly 30% of the time just doesnt make sense.
