Our defense is incredibly solid and 7 deep, scratching Lilleberg/Raddysh/Perbix is already a luxury most teams don't have. Defense is something I think you leave alone until the offseason anyways.
Getting our third line going would create the kind of matchup problems other teams had against us when we won the cup. This could be done by acquiring a tweener, or, we could even get a guy who's a legit top 6 forward like we were talking about pre-season, to come in and push everyone else down a notch.
We shouldn't be in a rush to do either, target the right guy and don't overpay this time.
