I think it's Rob's to lose (if not, Ravi), though I am surprised he didn't get the 5, instead. He has pretty solid chemistry with Cheryl, and I think there's a big risk of totally turning over the 4 within like a year (Alan now, Linda later), especially with new competition. Alan would've maintained stability in that slot, but I do understand keeping his daily airtime to only 90 minutes.
Fun fact: In his career with ABC 7, Alan has helmed 6 different "broadcasts". He was entrusted to launch two of them, the morning news and the midday webcast. And now, he has the right to say that he has succeeded John Drury, Floyd Klaber, Joel Daly, and Ron Magers, considered 4 of the very best to ever grace Chicago television screens. No pressure. Well deserved.
