Bob Costas isn't everybody's cup of tea but there's no doubt he loves the game a hundred times as much as Joe Buck, and they would be more likely to pinch somebody like Orel Hershisher or Dennis Eckersley than the dumbest guy in the room.
I don't mind Joe Buck too much, I think that he's okay and he was saddled with McCarver who was extremely tough to play off of for the last few years. However, one of the things that I like about this post is one of the reasons why I don't mind the hiring of Harold Reynolds; he loves baseball. Hershisher is really good and Eck is really good, but you weren't going to get them for a number of reasons (Orel is on ESPN and Eck doesn't want to travel), so hiring a guy that is exuberant and has obvious love for the game is important. As much as FOX's Game of the Week is for baseball fans, it's also important to snag people who aren't fans. I think that Reynolds has a chance to do that.
Am I ever going to learn something about baseball I didn't know from Reynolds? Honestly, probably not. But there aren't a lot of baseball color guys that I learn from, baseball's a pretty simple game and while there are nuances, you're not going to always get them from a washed-up athlete who is trying not to piss anyone off or say anything confrontational. You know why I like Eck? Because he's entertaining; he tells funny stories, he likes watching baseball and he has interesting names for ordinary things (fastball have hair, hard fastballs are cheese, etc). Every once in awhile he'll point something out, but normally it isn't anything completely mind-shattering.
EDIT: The other thing I don't want is a lecture. Baseball is fun, it's entertainment, it's something that I watch at the end of the day to unwind. I don't want someone throwing a ton of stats at me (chances are I can find them online on my own) or lecturing me about what a player is doing wrong. Because the latter can easily go down hill into a treatise on how today's players don't play the game properly, are lazy and don't respect the game. The kids are alright, grandpa.
I think that Reynolds will be just fine.
