Not that I have anything aginst Tyson Nash, but Murray is already a brilliant replacement for Begin, Downey is a mediocre replacement, and both Lapierre and Ferland are very good young replacements for Begin. Chipchura has the grit and the will, and frankly, I don't think we are short of pesky forwards with tons of heart, a varying degree of talent, and a varying degree of size.
That being said, the only reason I would be against having another guy like that (they are in fact my favourite type of player) is that we need all the roster spots we can get in Hamilton for guys like Locke, Grabo, Kost, Lapierre, Ferland, Aubin, D'ago, Urquart, Lemieux, and the free agents we picked up this summer for the Dogs. Plus Edmonton is already taking many of our spots.
