No, we don't need to spend any more assets on wingers, say what you will about the performance of late but any team that's regularly sitting Leivo and Kapanen, and has Soshnikov/Johnsson/Grundstrom in waiting behind them has lots of avenues to exhaust before looking for external help
We just finished a road trip that almost all teams who make it have found very difficult against good, big teams that suck to play against. We shouldn't do anything right now, catch our breath and not do anything knee jerk. We're still over .500 and the sky isn't falling, and even if this season takes a bad turn there's a ton of silver lining - get to trade your UFA's to keep their value, get a real look for some guys who have earned it in Leivo and Kapanen, might get better contracts in place with Marner/Nylander than we'd expected coming into the season, etc
