Deggs told a story about a kid from when he was at TXA&M. He said that he told Rawls the same story recently. Anyway, The player had a wipeout pitch that he couldn’t throw for strikes initially. The kid and the coach got into a verbal skirmish early in the season and he didn’t pitch again that year. After some mechanical changes in his delivery, 2 years later he was the conference pitcher of the year as their closer.
You gotta wonder if something similar happened here and I’m not talking about changing his arm angle.
