Philip Rivers is, IMO, the third best QB in the draft. Many draft analysts will agree with this; however, they believe he will be available in the second round. With Green Bay likely to draft Favre's understudy, I doubt Rivers will last until round two if he is the third QB taken.
Similarly, Vernon Carey is, IMO, the third best O-lineman in the draft. Again draft analysts will agree; however, they also believe that he will be avilable in the second round. Again, I doubt that he will be there.
Any talk of the fins trading down to take either Rivers or Carey, in reality, is ludacrus.
