A problem with this board it seems is that people are not looking at players' ages, like if it wasn't an obvious need. It's pretty normal for a player like Tkachuk if it took until he was 23 y/o to reach another level offensively. Looking at the last 2 years overall, Marner has a whooping 9 more points than Tkachuk at Even Strength

Marner is a great PPQB playmaker racking assists on the PP like a madman, but give me Tkachuk at ES.
It depends on the makeup of your team. Toronto has finesse and firepower, so Marner is more of the same. Swapping him for Tkachuk would improve their team, despite Marner being the better player. Kind of like how Chychrun wasn't a fit on Ottawa, so they traded him for an inferior player in Jensen as he is a much better fit. On the flipside, a team that has trouble scoring goals would probably benefit more from Marner distributing the puck as well as he does. He's one of the best point producers in the NHL, and while Tkachuks's skillset is more unique - Marner's isn't easy to come by either.
I think Sens fans would prefer to keep Tkachuk. I could be wrong (Leafs fans can chime in here) but I think Leafs fans would gladly swap Marner for Tkachuk. For this reason, I voted Tkachuk - but contract status plays a role and IDK if that's fiar as Marner is an upcoming UFA.
I don't know about Leafs fans but think about how FAST Toronto management would make that swap.
Age, contract status, cost, type of player, physical frame, goal scoring ability, intimidation factor, etc. Marner is a pretty good playmaker but Leafs would take Tkachuk in a heartbeat
