Servais was 2nd in AL manager of the year voting 2 years ago and 3rd last year. You know why? Because the people that vote on those types of things thought he did a pretty damn good job with what he had to work with.
Look man, Servais isn't perfect. I don't always agree with his decisions. I don't like how often Wong is playing. I don't like AJ Pollack starting over Kelenic. I don't like Moore starting in right field, having Teo at DH, and Ford on the bench. But here's the thing, I don't know the reasoning behind those decisions. There very well might be a good reason and we just don't know what that reason is. There's a million things going on with a baseball team that most fans are never going to be aware of.
I don't think Servais is some super amazing manager, but he's no where near as bad as you're making him out to be.
