man you are a tough audience. I thought Manning showed the potential to be dominating, when he commanded his secondaries.
But last season he was like where Mize was in 2020, rough, but too good to learn anything else against AAA hitters. He needs/needed the challenge of throwing all his pitches to big leaguers to sort out what is going to work for him and make the needed adjustments - like Mize had to move from the Split to more sliders once he faced big-leaguers.
