2010-11: In his freshmen year, T.J. Tynan scored 54 points in 44 games. He put his passing in display with 31 assists and showed he could finish as well with 23 goals playing with the Notre Dame Fighting Irish. In June’s draft, the Blue Jackets selected him with the 67th overall pick in the third round.
2011-12: His sophomore was solid as he set up 28 goals and scored another 13 in 39 games with the Irish. He had the honor of playing for his first US National team (USA U20) in the World Junior Championships U20. He scored four points in six games in the international tournament, his totals favoring assists once again.
2012-13: Tynan skated in all 41 games for Notre Dame in his junior season and was the team's fourth-leading scorer. He scored 10 goals (five on the power play) with 18 assists and was -1 with 28 penalty minutes. Notre Dame finished second in the CCHA behind Miami in the regular season but captured the last-ever CCHA playoff title, defeating seventh-place Michigan in the championship game. Tynan was named the CCHA tournament's MVP. The Fighting Irish lost to St. Cloud State in the Midwest Regional semifinals to finish the years 25-13-3.
Although Tynan’s stats did not show the promise they did during his freshman and sophomore seasons, his leadership ability was evident this year. He was a leader offensively and a passing machine. His size is still in question, but the 21-year-old is quietly developing a sound technical two-way game.
Tynan’s senior season will need to contain more consistency than his junior year. He has proven that he can score in the clutch, but needs to perform on a nightly basis. Following this season, Tynan will have a chance to make his professional debut with Springfield.
