What are some under the radar contracts that you think will age horribly?

Mikko Rantanen, depending on how that shakes out.

A guy who's going to be 29, and has spent his whole career being his team's third-best player, getting $14m to carry a team makes me nervous.

It's underappreciated just how difficult this task is furthered by Rantanen being a winger. If you look around the league, how many wingers carry their team to a reputable level and are worth their cost? 3?
