It's my experience that there's usually a grain of truth behind what Baldi says. But you need to ignore his final conclusion.
Ex: Baldi says Harrison is leaving last summer, more respected posters admit several months later that he flirted with OK State.
Ex: he says Lavin is gone, and it's a done deal. Other sources then point out that Lav put out feelers for the Cal job and no extension has been discussed in a long time.
He might say its a done deal or it's going to happen on x date ...and that is almost always wrong. But a vast majority of the time, I look at the substance behind his claim, because it's usually true - he (or his source) just jumps to conclusions. If he says a player is transferring tomorrow, I take that to mean that that player is unhappy or is in coach's doghouse.
If you look at it that way, he's almost always right.
