Morning Show = Free Evening Shift?

Morning shows, are now repeating at night too. KENZ "107-5 The End" is currently repeating it's morning show as a "best of" with what they call "the night shift." KISN 97 is also repeating the "80's Chain Reaction" part of it's morning show, "The Rockett Radio Experience", at night. Could this lead to other stations, pulling similar actions? Other stations that use the point-to-point or time-delay "voicetrack" technology also include KKAT (K102) and KSFI (FM 100). KKAT's morning show, "Tim and Willie," are from Pheonix, voicetracked to sound local. FM 100, Utah's #1 rated station, uses a "canned" (or recorded) Bob Nelson for the night shift, allowing his talent to be used twice, and cut costs of hiring an evening talent
