The expectations for Benn at this point shouldn't be very high. The 35-year-old defender hasn't played a full season since 2019-2020, and has averaged no more than 16:17 of TOI in the past three years. The best role for the Victoria, BC native would be as a depth defenseman, but this is a great opportunity to develop some chemistry with Rielly, who will likely lead all Leafs defensemen in ice time this season.
It will be interesting to see what the final defense pairings will be. With Liljegren being injured, Muzzin having some issues with his back and Sandin still unsigned, there is a lot of opportunity for new defensemen to prove to the organization for why they should be in the lineup come October 12th.
