I would like to add Glaus even though I don't have daily room for him to play. He may be a valuable trade chip. He is statistically identical to Cantu but from some reason nobody in my league will trade for Cantu.
So should I drop Posey, Weiter who is killing me, Cantu, or hold and ignore Glaus?
Tough question. Wieters is bound to pick it up at some point. He had the same hype as Posey, and perhaps more, at one point. Glaus is a ticking time bomb in my eyes. Although, why not ride the hot bat. You have no UTIL spot? If not, you'd have to take out Reynolds, who is pretty much what you expected, I'm sure. His average can't go any lower.
So, I'd drop one of your catchers and ride Glaus/Reynolds, whoever is on a hot streak. May as well dump Wieters for now while Posey is hot.
If you have a league full of guys who pay attention and one of them is having catcher problems you may be able to trade Posey if you believe that Weiters will come around. Posey has too much hype to drop.
I also agree about Glaus. He is not going to hit this well for huge extended periods of time. If he continues this streak into mid-end of June you may be able to unload him before he turns to ice.
