Definitely a little strange. I don't like it. But I also don't know if I should care.
I thought Bosio was a great pitching coach. But, then again, all of our pitchers started throwing 4 mph slower this year and we walked like 7 per 9 innings. So what the hell does he know?
I'm honestly not sure how much affect hitting and pitching coaches have. I think having good organizational approaches is important. And it's obviously better to have a pitching coach who is more knowledgeable. But all of that work is done behind the scenes, so it's hard for us to know exactly how significant a coach's impact is. You can look at results, but that's a fool's errand.
So I'm not a huge fan of this move, but I'm not going to get too worked up about it.
