In June, receiver Percy Harvin asked the Vikings to trade him. He later changed his mind.

Now, his mind could be changing back again.

In the aftermath of a report this week from Tom Pelissero of 1500ESPN.com that Harvin and coach Leslie Frazier engaged in a “heated exchange” before Harvin’s placement on injured reserve, there is plenty of scuttlebutt regarding the question of whether Harvin will ask again to be traded — and whether this time the Vikings will decide to grant his request.

Though he is one of the best offensive players in the league, Harvin has been a headache for the Vikings for most of his career. He battled with former coach Brad Childress, and the fact that Harvin has gotten under the skin of current coach Leslie Frazier, who is as even-keeled and low key as any coach at any level of the sport, speaks volumes to the problems Percy has caused.

Then there’s the fact that he surely will want to be paid huge money before his rookie contract expires after the 2013 season, and that’s an investment the Vikings may not want to make.

Harvin’s salary expectations won’t make it any easier to trade him. At a minimum, what the next team will have to pay Harvin likely will reduce whatever package is available to Minnesota in the form of pick(s) or player(s).

As the Vikings push toward the postseason without Percy, they may decide that, in the long run, they’re better off without him.
