The point is Cumulus spent a lot of money to hire top notch experienced news professionals.
The problem was they were National and International reporters. They had to accept what Fox 5 had locally until they could build up local contacts. WSB at that time had access to the AJC newsroom, and Channel 2 also WSB had (has) better (ratings wise) talkers when 106.7 tried talk.
IMHO it would take at least 2 years to build the local "trust" for a really good local news gathering effort from scratch. 106.7 never got the time because Cumulus didn't have the capital to be successful.
