Bengals haven't done enough to address O-line problems.

I bet they are also looking at Tretter. if he's a fit, then Karras moves to LG.
Hopkins would likely be released in that scenario. As Karras would be Back up C, and Carman back up LG.

Then only thing is find a 1-2 year placeholding vet and draft/develop a RT.
