I'm not sold on getting rid of Howard. If Sam really is gone (and I think he is given his comments), it makes a degree of sense to think that it is being done because Nick sees something in Howard he thinks is okay enough to keep him (hopefully at a discount). I'm frustrated with his play as a Dolphin just like everybody else here, but I'm willing to let Nick do what he does best and make strategic moves.
The right QB you're speaking of is named Jon Kitna if you ask me. I'm growing convinced that Kitna plus Croyle on the second day is the answer. That 40+ yard perfect throw BC had into double coverage just cemented it in my mind.
