I think Semien SS, Bo 3B and Biggio 2B is the only logical position swap we can do amongst those 3. Personally I don't think any of those guys can or will play 3B.
3B is usually reserved for bigger players with a great arm and hands. You can help offset your shortcomings in those categories by being elite in another. Can't think of many small players like Bo who have his hands succeeding at the hot corner.
Semien is on a 1 year contact who is looking for a big pay day. Last thing he wants is to play a position he hasn't played much before and ruin his value in any way. Would shock me if he plays there in any full time role this season.
