steelerstime recently pointed out that the Rochester Rough Riders reported to ST with a Fielding Instructor that sported a Glove IQ of 8. Subsequently, some of Rochester's young talent took hits in their ability to field and catch the ball, as evidenced here: Tiny Allen, Henry Siddall, Tyler Buhner, Jimmy Little, and so on. steelerstime was kind enough to submit a ticket on this to admin, and they have replaced Rochester's original FI with another, slightly better version: Groucho Lesher.
This got me to wondering what other coaches out there that may do damage to their squads. The good news is that there aren't many. Nine seasons into Capra, we have seen more quality coaches and IQ improvements than retirements, making it easier to land solid staffs and harder to get stuck with a stinker.
At the big league level, the lowest rated Pitching coach(Jaret Fyhrie) sports a 76 IQ, a respectable # that would have been a mid-grade pitching coach for Capra's first 4-5 seasons. Same goes for the S9's worst Hitting coach, Dewey Charleston, who has ironically run San Juan's murderous offense for three prior seasons. Play with that one.
Worst Bullpen coach is a 68(Lonnie Marshall). The worst Leather Instructor is not even Lesher. Colorado's Chico Valdes now owns the honor at 49, and the Bombers youngsters seemed to feel no ill effects in their ST development. The lowest strategy IQ amongst Bench coaches is the Royales' Cliff Grabowski, but, of course, Bench coaches aren't specialists in one area and Grabowski is in the middle of the pack in all other coaching intelligences.
As far as base coaches go, it's easy to point out those with a low baserunning knowledge, but some owners employ the strategy of hiring high hitting IQs here(Bono Gibbons, Brady Gates), though there are some who sport neither(Andres Mota, Barney Sirotka, Earl Hayes).
Conclusion: There appear to be no more coaching tragedies awaiting any big league teams this season, save for stalled development and plenty of runners thrown out on the basepaths. I did spot a few terrifying minor league coaches, but that may be another post.
