Yeah, Charlie's only/main skill seems to be dealing with players (it's certainly not in-game stuff), so for him to make that quote about Kikuchi is pretty alarming. Although to be fair, it's infuriating as a fan to watch Kikuchi when he's not on, so I can imagine it being a lot worse in the field and dugout when you're playing behind him.
As far as Biggio, it seems the organization (Charlie plus everyone else) thinks that Tapia has more potential. The most logical thing to do, especially when he's on a hot streak, is to play Biggio everyday all over the field. That's really the only way this "we need to DH regulars everyday" concept makes any sense, when you plug a good player into different spots so the regular can DH. For them to be using that on a -0.6 WAR player instead is baffling. It's something bad organizations do, not what the Jays should be doing.
The Jays are in a playoff spot, and probably will get a WC spot when all is said and done (unless the Mariners go crazy in the 2nd half.....can't see anyone else as a threat), but man is this team flawed and not fun to watch right now. Although this could work out in the end if they hold on to the 3rd WC spot at the end of the season and face the Twins in the WC round instead of Red Sox/Rays.
