Percy Harvin returns to practice, but is he a liability to have on the team?

          Friday, November 12th, Percy Harvin of the Minnesota Vikings returned to practice as he has suffered severely from migraine headaches this past season. Percy has missed the past two practices due to these painful headaches, and Brad Childress (the Viking's coach) even said they haven't completely cleared. He is even doubtful to play this Sunday against the Bears, which is a detriment to the team as Percy is a vital Wideout to this team. Harvin has also been dealing with a sprained ankle, but is nothing to worry about as the migraines are more of a bigger issue. It always seems that Percy Harvin is always doubtful, or encounters limited reps because of the migraine issues. I do not disagree with the precautions they set on Percy so he does not get any concussions, but I think it may just be time for the Vikings and Harvin to part ways. With the payload he is receiving, and the outcome he is producing on the field, I just feel that the two do not balance out and this waste of money is not needed. Although Percy Harvin is a tremendous talent, he cannot play to his full potential with his migraine issues. The 5 year, $12.05 million dollar contract starting back from the 2009-2010 season would be a respectable deal if Harvin had no uncertain week by week issues. I would believe this uncertainty would be too much to gamble on, but who knows what will happen with the Vikings and Harvin. All we can do is wait and see...
