While the major league club tries to figure out exactly what it is going to be and who is going to fill certain positions, the various affiliates have their own host of storylines that we will be following in Mesa this spring. The primary topic to keep an eye on is which prospects are assigned to each affiliate. The Cubs have about 125 guys to squeeze into 50 spots at South Bend and Myrtle Beach, then another 75-80 competing for spots in Iowa and Tennessee.
Rotation and relief spots are always among the key position battles, but catcher and middle infield are going to be up for grabs at every level.
