Exactly. A professional athlete needs to know their body almost like a violinist knows his instrument or a driver knows his car. Price dominated with a big fastball coming off a big frame. His 97 looked like 100 since he was throwing it closer to the plate than most at his incredible height. He needs to adjust. He likes to go up to get strikes, either foul balls or swinging. He needs to stop doing that in the zone. He likes to drop a cutter down in the zone to try and get ground balls. Well, without the same velocity, those balls are being hit harder and not necessarily on the ground. He needs to bring those balls down further in the zone to get more of the same effect. As your velocity wanes, your effective strike zone shrinks incredibly. He needs to chop a few mph off his breaking stuff. His cutter is only 4mph off from his fastball now. In his hay day, it was 6 or 7mph. His changeup differential used to be 9-11mph difference, now it is 7mph difference. He needs to slow down his change and his cutter to maximize his deception. A hitter only needs to adjust location and not timing with a 4mph difference on cut vs 4 seamer. If it is 6 or 7mph, he will be early and will have to adjust location as it moves.
