Here is my understanding . . .
Negatives - for those who think RTan is average, Cutler is no better.
For those who think he could have been top third, Cutler is a mild
downgrade. Most think Cutler is better than MM. Throughout his career,
Cutler has been a 'meh' QB. Not bad, but not capable of "carrying his
team."
Positives - smart, not reckless (i.e., MM). Already knows the system,
already has a hx with Gase.
For those looking for hope, Cutler's D was seldom good and receivers
less than average (think RTan under Queasy). In Miami, the receivers
appear quite good, good run game (predicted), and the D should improve
to average (that's a BIG jump). Personally, I was never a Cutler fan,
but never had anything against him, thus, agnostic.
For the record, the 'other' options seemed to be limited to Keap
(please, NO), and Osweiller(sp?). If those were my choices, I MAY have
gone Cutler. I say "MAY have" because I was leaning towards giving it
to MM and take my chances.
