Cutler trade, back in 2009, actually made sense then. he was young, alternate or not came off a Pro Bowl, and certainly could have been more explosive than Orton. having Ron Turner and Pep Hamilton etc. began the stunting, then he had a couple decent years with Martz, then he gets stuck with clueless Tice. then completely falls off the deep end in the Trestman years.
I think if there was competent coaching consistency on offense we wouldn't even be arguing about this today. even if he was middle of the road and seemingly didn't cost the team games (he hasn't in the last 3 years at least) people wouldn't be going off about how they need to unload him.
I personally thought Orton was decent. the team by time he was starter had missed on a couple drafts and the offensive line was getting a little bad. the receivers were a joke until Marshall was brought in, which was during a new array of issues on offense.
realistically there was always some crucial piece missing, 2013 season excluded where Josh McCown looked like a world beater. the team is sad, guys.
