From Feb thru the draft, the draft "experts" are constantly talking about rising and falling prospects. The GMs I have heard consistently state that their draft boards are complete before the combine and change very little after that time. I tend to believe the GMs. I think all the rising and falling stuff in the minds of the "experts". Excepting undisclosed stuff coming out like DUIs or injuries, I doubt players jump on the teams' boards from the end of the first round to the top after wonderful performances at the Senior Bowl or Combine. For example, if Floyd or Ansah go in the top five picks, I cannot imagine they rose up on GMs boards from the bottom of round 1 (where they were in mocks I saw a month or two ago).
