Kitchener is a veteran team ranked near the top in the country, so this is the year that you want to go for it. I've mentioned this before, but I think the Rangers should make a push for both Dal Colle and Vande Sompel. Not only do you have enough assets to acquire both players, but they are precisely the type of players you need (Dal Colle, secondary scoring, PP; VDS, offensive d-man, PP QB).
I also think that if you could pick up those two, both Erie and London (more so the former) would be hardpressed to counter that move with moves of their own.
Wait a second, what am I saying?...too much Bailey's in the coffee this morning. On second thought, stand pat, go for it next season. I'm not supposed to be giving advice to the enemy!
