Boucher agreed to terms on a three-year, entry-level contract with Ottawa on Tuesday.
Boucher -- who was selected 10th overall in the 2021 NHL Draft -- appeared in 17 games for Boston University this season in which he tallied three points, 34 PIM and a minus-6 rating but will now join OHL Ottawa. The 18-year-old will likely have to spend some time in the minors before getting a chance to crack the Senators' lineup but is worth monitoring in deeper dynasty formats.
