If it's me (and my name is Lou too

), if the team is in a playoff positions come the deadline, at least with forwards I stand pat. Go with the guys that brought you to the dance, and save the assets.
On the back end, though, because regardless of the playoff position, I'd be looking to trade one of (if not both) of Polak and Hunwick, you probably look to replace them. A healthy Marincin probably takes one of their spots, but if you don't trust Corrado and the price is right, maybe you bring in a veteran guy to be that #6 D man? Johnny Oduya? Brendan Smith? Cody Franson?
Not a priority, though. Again, this isn't the year you go for broke. Keep as many picks as possible and keep building the team through the draft.
