Have Cubs hired Derek Johnson replacement yet as pitching coordinator? Johnson was very, very well respected, so may be hard to find his equal.
Still, always possible that a new guy might come in who's got a few really good new ideas of his own, or who can perhaps notice some delivery flaws and solutions that Johnson didn't? Or maybe who just has an ability to connect with a few guys and help them out? Would be fun to add some value.
OK, the power of Google! Jim Brower, 43, 8-team journeyman plus Japan and Italy and lots of minor-league stops as a player. 5 years coaching in Kansas City system, last three in AA. Hey, he's a Minnesota kid, he's going to be great! I imagine being a journeyman like that exposes to a lot of different pitching coaches, and probably a lot of different teammates with different ideas. If one voice gets old, he's probably heard a lot of them, and could have accumulated a lot of good ideas.
Cubs generally seem to be pretty shrewd on the personnel side, so I've got to assume he's a capable guy.
