I would hate to see Dann Florek go, he's one of my favorite L&O actors of all time. I can understand why it might happen, but I still hate it. Cragen rocks!
As for Benson: If she does take over the squad, I bet Munch would be only too happy to let her (he hates it when he has to run things, he only took the Sergeant's exam on a bar bet
). I wonder if Benson could go straight to Lieutenant without being a Sergeant first...
And FWIW, I miss Stabler.
