Entering the 2014–15 season as the only 17-year-old to play in his third year with TPS, Mikko signed a two-year extension to remain with the Liiga outfit on October 9, 2014. Through using his big frame and physical play, he recorded career high 9 goals and 28 points in 56 games, also serving as an Alternate captain.
Mikko also featured for TPS junior club in the post-season recording 14 points in 7 contests to help capture the Championship and was given Best Player honors for his efforts.

On 13 July 2015, Mikko was signed to a three-year, entry-level contract with the Colorado Avalanche. After attending his first Avalanche training camp and impressing in the pre-season, he was announced to have made the opening night roster for the 2015–16 season as an 18-year old on 6 October 2015.
On October 8, 2015, Mikko made his NHL debut to open the season with the Avalanche in a 5-4 defeat to the Minnesota Wild. He was used in a depth role and played limited minutes over six scoreless games with Colorado before he was sent to AHL affiliate, the San Antonio Rampage on 22 October 2015.
In his AHL debut, Mikko contributed with his first goal and assist in North America during a 5-1 victory over the Stockton Heat on October 24, 2015. He continued his scoring pace with the Rampage, leading the club in all offensive categories before he was selected to the AHL All-Star Game as the second-youngest participant in the event's modern history.
After receiving a three-game recall to the Avalanche, he was returned to complete the season with San Antonio, becoming just the seventh teenager to reach the 60 point mark in 52 games.
In finishing 6th in overall scoring, Mikko earned a selection to the Second All-Star Team and shared the Dudley "Red" Garrett Memorial Award, alongside Frank Vatrano as the League's rookie of the year.
