Loved Manning as a player and believe that he could be a great HC in the future. That aside, he won't be here unless Shelly whiffed on a lot of guys. Outside of the HR hires, I really think this focuses on one ability: rebuilding. If you can do it, you're in the conversation. Manning really hasn't proven he can, but neither have Miller or other guys that we discuss here outside of Howland. There doesn't seem to be a lot of program-builders out there, but it's not my job to find them so I don't really know. Nonetheless, If he is trying to "win the press-conference" with Manning, I think he could for many. For us, no.
Somewhere I swear I read (or saw at the PC) that he said hunches and gut-feelings were out of consideration for the next hire. If Manning is the guy, it's a pretty big hunch/gut-feeling. As a result, there's very little chance Manning is the guy in my mind.
