My finals record has been terrible so far, so not playing sides or totals but I think I do have one nice pick for game 4.
Nathan Mackinnon Over 4.5 Shots on Goal(-130); Has yet to score a goal in this series, and was the leading scorer for the Avs in the playoffs. In postgame interviews after game 3 he was adamant that he needed to get going in this finals, and he was on the team to score. So I expect Mackinnon to be aggressive in this game. He had 6 shots on goal in game 3, and has gone 4-1 over this mark in the last 5 games.
Good luck.
