It's not a matter of how he fights, it's THAT he fights.
He may lose, but if he loses to Iginla he takes Iginla out of the game.
He may not be in the top percentile in any one catagory.... ie fastest skater, best puck handler.
but his overall skills are better than those who are vying for a spot.
R1:
Burrows vs. Pettinger
Burrow wins, less speed but more grit and willingness to go to the dirty areas
R2:
Burrows vs. Rypien
This one is close, I think they are virtually the same player, and experience leans in Burrows' favour. However Rypien is a much better fighter. It's boils down to: how many fighters do you really need on this team? Also, Burrows has already proven himself in his own zone. Rypien kills penalties in Manitoba but can he do it at the NHL level?
R3:
Burrows vs. Brown
Again very close, Brown is by far a much smoother skater, is much tougher, and so far has shown more offensive talent. I'd say that this is a coin-toss but Burrows and Kesler have chemistry, that is also a factor.
In the end my depth chart for an agitator would be, Burrows, Brown, Rypien.......
Let him play out the season and earn his raise, if he becomes more expensive, then he's expendable....
At his current price, keep him... Brown is waiting in the wings and would easily slot in, if Burrows goes to Pittsburgh (a la Ruutu, a la Cooke)
We seem to just cycle agitators anyways. Get as much out of them at basement prices and let them go.
