It really sucks if Didi leaves, but like SFD said, there's a big logjam in the infield. Personally, I'd prefer to go into camp with Didi at short, Gleyber at 2B, make 3B a competition between Urshela and Andujar, let Voit, Ford, and Bird battle for 1B, and keep LaMahieu as the everyday gives-someone-the-day-off man.
