So say we keep Killorn either because BriseBois doesn't want to trade him or he doesn't want to break up our new shutdown line. Then would you rather have Palat or Paul? For this exercise let's assume Paul signs a 3.5x3 deal and Palat signs 4x4.
I personally would pick Palat because he's such an asset as a top line winger and a good 3rd liner is easier to trade for in the offseason or at the deadline. The only scenario where I could see myself preferring Paul is if we trade Sergachev for a high end young forward who we'd really want to play in the top 6 (ex: Sharangovich).
