Grace says he's progressing well, but if it were up to him, he'd play in crutches. Get Sammy to be a complete ball player again. His fielding, base running and throwing seems worse than last year. Use pitchers that throw strikes. There seem to be more walks than ever.
Managers have much less impact on wins and losses than coaches in other sports.
As you point out, Baylor spent all spring telling his relievers not to issue walks. Throw Ball 1. Then Ball 2. Then Ball 3. You get the picture.
