I agree that Cumulus overpaid for Citadel big time. Lew & John had delusions of grandeur and desperately wanted their crappy company to be viewed in the same vein as CBS Radio and iHeartMedia (Clear Channel at the time).
The irony is - the incumbent Cumulus stations were already showing signs of stress.
John Dickey and Jan Jeffries literally thought they could hand program hundreds of different of radio stations themselves with minimal local input and deficient research. Post Citadel acquisition, remember John Dickey's "reverse crossover" gimmick he forced upon some of his company's country stations? Stations such as 96.3 KSCS in Dallas/Ft. Worth started to play a couple pure Hot AC-type songs an hour. This bit of programming idiocy sent the ratings crashing through the floor. Firing Jack Diamond & gang from Mix 107.3 in Washington in favor of a piped-in morning show from Atlanta (yes, I realize Bert Weiss once worked for Mix 107.3) was another example of programming brilliance. Within six months, what was once a perennial revenue powerhouse was completely ruined.
