Very debatable that Flacco is better at this point. Also, very debatable that the bandaid is better... most often teams end up in "stuck in mediocrity" with the bandaid approach as opposed to "blowing it up". Bears fans should know this very well firsthand...
IMO, I think Flacco is am upgrade. The Broncos will aim to make their defense even better and Flacco actually gets receivers in Denver. Something he hasn't had in a few years. It'll be interesting to see how this all plays out for the Broncos.
