I hope that (and think that it is highly possible that) the team will fill in the blanks with intention of moving Harrison into the CAM. He was great at wing (at times), and certainly played above expectations as a rookie, but I think that he is more naturally a high attacking MF. Some of his best plays this season were when he had drifted to a central role during the run of play and was distributing the ball to wings (for example, his pass to Shelton against Columbus) or bull rushing through the middle (for example, his run against Philly with the ultimate back pass to Villa). I think that some of his vision, distribution, burst and craftiness were lost on the wing where he would often just put his head down and proceed vertically. He also has the speed and work rate to help out defensively if necessary, although we haven't seen his capabilities yet in that facet. If it works, you would see a lot more cohesion in the middle of the field than you saw with the clunkier version given Lamp's strengths and weaknesses.
Of course, a lot will depend on the other pieces. I hope that JH ends up in the middle.

Tom in Fairfield CT making this point as well.)
