From everything I've heard or read, CBS would prefer to get out of slow growth, no growth, or declining markets like Cleveland.
Problem is...nobody's buying stations except at dirt-cheap prices...and most owners/groups don't want to take huge losses in order to leave, unless the situation becomes so dire and unbearable it's a "cut your losses" situation. (wonder if Next Media in Canton is nearing that point in time?).
So, CBS is being proactive and investing in their Cleveland cluster. If 92.3 The Fan does great, it would seem like the next move is taking that format to 98.5...and letting classic rock WNCX play out the string on 92.3. The cluster grows, becomes more profitable...so that having to keep their 4 stations in Cleveland becomes less of a drain/hassle on CBS corporate....and, maybe some day, they can sell at closer to what they're looking for.
But, buy more stations in Cleveland? Ahhh...that might be too much of an investment for CBS (or even CC) to want to risk in the economically declining rust belt...unless the price is so low it's insane not to buy.
