I would not bet on any of those 3 "what ifs," but JBJ will be given a chance to hit, Arroyo will be given a chance to play and Duran will be given a shot, if he can hit. (Yes, perhaps a big if.)
My guess is Kike will end up playing at 2B, CF or even RF depending on the answers to these what ifs.
Personally, I want Kike in CF as much as possible, but I realize it may not happen, especially with so many moving parts, including the possibility we add a solid OF/er by opening day.
