I'm going to laugh and laugh and laugh if Tatar signs a more "team friendly" deal than Dekeyser. Everybody is overly worried about Tatar, but the local guy isn't signed either. What if he's the one with the "ego problem" or whatever else is being suggested about Tatar? People act like Tatar is some kind of bad seed because he's trying to get the best deal he can. But clearly Dekeyser is doing the same thing and everyone is mum.
Truth is, neither are currently signed because their value is really hard to determine. They've both played better than your average rookie but don't have a track record. As such, it's hard for both management, and their agents, to figure out what their proper value is. So it takes time.
