1) He has yet to prove he is worth anything more.
2) Because I'd happily pay 10m for a player that he's been for the most of his career, for the next few years at 1B, rather than worry about this position and trying to shoehorn prospects into all the time, but I accept we can wait on this, though it might end up costing us more if we don't jump on this down year.
3) Trades can be used for anything including for unloading as we've seen to great effect at this organisation. Whether we can do what I've suggested is another thing - I said it would be difficult/unlikely. Yoshida is more or less useless to us. and along with Casas has little to no value, which is why if you're lucky enough to get a taker, you do it immediately. Literally immediately.
4) We'll have to agree to disagree here. I'd be over the moon to have those 4 rotating, with Password as the RH back up, assuming he can hold his own. Several different skill sets, and 4 very good options, with one prospect.
For SP I'd like - Crotchet, Bello, bring back Gio, and see if Cease wants a year where he tries to rebuild his value, and then we have Crawford, Dobbins, Harrison, Tolle, Sandlin and Early waiting to take the 5th spot and give us depth. That would be just fine by me,
