As much as I love Almora, I would do it with him as the centerpiece. Maybe Almora, Johnson, and Candelario. Although I'd rather have Soler as the centerpiece.
Rizzo's babip is like .240 and his LD% is close to 20%. I don't think he'll ever hit .280, but .260/.350/.500 is still a realistic expectation for him going forward.
Would still love to have him back, although I'm not familiar if there are any good backup catchers in the FA market this year. Their certainly are not any in the system.
In the next 6-18 months, the IF is going to see that first "waive" of talent. By ST 2015, you'll have: Rizzo Castro Barney Valbuena Olt Villanueva Baez Alcantara Bryant all vying for 4 infield spots. If Barney is with the Cubs in ST 2015 I might hang myself.
