Robert Feder (@robertfeder) writes this morning that the White Sox' radio contract is up for renewal, and WLS and WGN are vying for the rights against the incumbent, WSCR. Like the Cubs' new flagship, WBBM, WSCR is owned by CBS, and Feder says 'BBM's contract with the Cubs would allow them to move the Cubs over to WSCR if The Score can't retain the White Sox.
In other words, come next spring, the Cubs could be on The Score, and the 29th-best baseball broadcasting team on radio could be on WGN.
Related aside: the Cubs' move to WBBM hasn't detracted one iota from my enjoyment of, and interest in, this Cubs season.
