6. Logan Brown
It has taken Logan Brown a bit longer than first expected to develop, but the 11th overall pick at the 2016 NHL Entry Draft took some big strides this season. The 22-year-old appeared in just 48 games total this season, 25 coming with Belleville and the other 23 with Ottawa.
His totals with Ottawa weren’t great, with just one goal and eight points in 23 games. However, with Belleville, he was able to put up seven goals and 28 points in 25 games. The six-foot-six centerman will more than likely start next season in Ottawa, and has a chance to become a game-changer due to both his playmaking ability and his size.
5. Alex Formenton
Though it was a disappointing season for the Senators, many of their prospects had fantastic seasons, none better than Alex Formenton. The 20-year-old left-winger who was taken 47th overall at the 2017 NHL Entry draft had an injury-riddled 2018-19 season in the OHL. When he was able to play, he was rather average, posting 13 goals and 34 points in 31 games.
He still entered the 2019-20 season as a promising prospect, however not many were expecting his first professional season to go as well as it did. Formenton was terrific for the Belleville Senators, finishing the season third in team scoring with 27 goals and 53 points in 61 games. He will be pushing for a spot with the Senators going into next seasons training camp.
