The Toronto Maple Leafs made the blockbuster move to acquire the former Conn Smythe winner and it has paid dividends with the regular season coming to a close. Yes, he was injured for a month with a broken finger and the Leafs took their time in bringing him back, but he still scored 4 goals and 11 points in 13 games. In fact, he only registered 12 goals and 19 points in his first 40 games with the Blues, was a -24 rating, and averaged 18:24 TOI. In just 13 games with the Leafs he was a near point-per-game player but more importantly he was a +11. Plus/minus is a very controversial stat, sometimes cherry picked to make an argument, but there's a massive difference between being -24 and being +11 - regardless of team performance.
O'Reilly made his return from injury against the Boston Bruins in their eventual overtime loss and didn't record a point. However, the next 4 games, he registered a goal and 5 assists to close out the season, including a 3-assist night against the Montreal Canadiens.
He is going to be the ace-in-the-hole for the Leafs in the post-season. He can play either on the wing or down the middle, and he brings a lot of leadership and experience to a Leafs locker room that needs it more than ever. He also has 22 goals and 56 points in 64 playoff games and a Stanley Cup ring, so that's not too shabby either.
