The Boston Bruins have one major problem with their roster, and Don Sweeney may have to make a trade to fix it before it's too late.

It's clear that the Boston Bruins have been missing a real top-six forward, especially ever since Jake DeBrusk ended up leaving the organization.

Sweeney ended up trading for Viktor Arvidsson from the Edmonton Oilers in the off-season, in hopes he could be a top-six player for them, but that hasn't worked out.

During the off-season, instead of targeting a top-six player, Sweeney decided to sign multiple bottom-six players to try and help their depth out.

Boston's depth has seen a major improvement from this, but now it's clear that there is a big problem in the top-six, and a trade may need to happen.

Bruins have a clear problem in their top-six

The Bruins top-six has not been good for them throughout the past couple of games, and because of this, Marco Sturm has made some changes.

Leading up to the game, Sturm made lineup changes top the top-six, and bottom-six, and throughout the game he ended up making more changes.

Michael Eyssimont, who was a depth signing for the Bruins, ended up getting placed on the top line with David Pastrnak and Elias Lindholm at some point during the game.

This is a clear problem for the Bruins, as there is no reason a bottom-six player should be in the top-six.

Eyssimont was brought in to be a depth player for the Bruins.

Don Sweeney needs to figure this out soon, before this season turns ugly once again for the Bruins.
