The rumors keep on coming. Now The NY Post reports insiders are whispering that ex-N.Y. Jets quarterback Boomer Esiason will permanently replace Imus in the morning-show slot on CBS-owned WFAN. Boomer, who went into broadcasting after retiring from his football career in 1997, was the first tryout after Imus was fired. We hear no one has been signed yet, either way. We think Imus himself may be back, as other rumors have been stating.
