Keep in mind that the Sox told Morel that when he's ready, the 3B job is pretty much his. Teahen, even with his extension, will not be a roadblock. There's an interview from a month or so ago where he mentions this. He was asked how he felt about being stuck behind Teahen, and apparently they basically told him not to worry about it, he's going to be their guy.
Sox may be higher on Morel than you think. That doesn't mean Kenny won't deal him, he'll deal anyone, but I don't think it's as likely as you guys are making it seem.
