"... but CC will go down swinging to keep [the Browns]...they mean too much to WMMS especially."
You overstate the team's importance to WMMS. The average WMMS PPM for January through July 2012 was 4.66. The average since August, when the Browns preseason began, is 4.95. The average for August through Holiday 2011 was 4.74. WMMS, as a rock/talk hybrid, has built a loyal following completely separate from its role as the Browns' FM flagship. Rover, Alan Cox, and Maxwell have accounted for nearly all the station's growth in the last five years. Before Rover, the station routinely failed to crack the top 15. Then the Spring 2008 diary came along, and WMMS found itself at #8.
Clear Channel has more to lose than gain here. WMMS itself will remain largely unaffected. WMMS in 2012 is not the same as WMMS in 2002, a time when the station actually needed the Browns to stay afloat. Interestingly, Mr. Hammond's article quotes an "industry source" who reminds us that Clear Channel does indeed have other stations in its Cleveland cluster.
