Vikings receiver Percy Harvin is one of the most explosive players in the NFL. In more ways than one.

His fierce skills come with a fiery (at times) demeanor. The latter reportedly manifested itself earlier this month, via a “heated exchange” with coach Leslie Frazier.

Tom Pelissero of 1500ESPN.com reports, citing “four NFL sources,” that Harvin and Frazier argued “in front of some players and staff members.” That would be at least the second incident between player and coach this season; previously, Harvin was seen jawing at Frazier during a game at Seattle — the same game in which Harvin suffered his ankle injury. During the offseason, Harvin was upset about something other than his contract, and he asked for a trade.

Per Pelissero, some believe that the second argument, not the ankle injury, prompted the decision to put Harvin on injured reserve for the bulk of the season.

If the report is true (and we’ve got no reason to think it isn’t), it’s the latest in a long line of incidents involving Harvin. He clashed with former Vikings coach Brad Childress, with Frazier playing the role of peacemaker more than once. And at Florida, Harvin reportedly grabbed receivers coach Billy Gonzales by the neck and threw him to the ground. Harvin was never disciplined.

The end result could be a decision by the Vikings to get what they can for the 2009 NFL offensive rookie of the year and move on. What they get — and what he’ll get by way of a second contract — could be influenced by his history. Eventually, however, someone will take a chance on a guy who gives any team a better chance to win.
