2007-08: Jokinen completed his senior season at Cloquet-Esko-Carlton, where he served as one of the team captains, leading the Lumberjacks to their first Section 7AA Championship since 2002 and a berth in the Minnesota state high school tournament. His 43 points (22 goals, 21 assists) led CEC in scoring and ranked fourth in Section 7AA overall scoring. Jokinen garnered numerous accolades that included being selected to the CCM All-Star game, earning an honorable mention to the AP All-State Team and being named a finalist for the 2008 Mr. Hockey Award. Most recently, he was selected to participate in the 24th annual Chicago Showcase.
2008-09: This was the wingers first season with Minnesota State University – Mankato (WCHA). In 24 games he netted three goals and five points.
2009-10: Jokinen had a limited role in his sophomore season with Minnesota State. He appeared in 24 of 39 games for the Mavericks, who finished tied for eight in the ten-team WCHA. Jokinen scored 3 goals with 1 assist and was an even plus/minus with 14 PMs.
2010-11: Jokinen was one of six players to appear in all 38 games for the Mavericks as a junior and posted his best offensive numbers to date – scoring 9 goals with 8 assists while receiving 24 PMs. On the downside, the Mavericks finished 11th of the 12 teams in the expanded WCHA and Jokinen's -12 plus/minus was the team's lowest.
Jokinen possesses all the attributes on offense that a scout looks for in a young player: skating, vision, a hard and accurate shot, and the ability to pass the puck as well as finish. At this point, he needs to get in the weight room and add bulk to his tall frame. Although he uses his size effectively and has a physical element to his game, he does need to improve on defense.
Jokinen is mostly a borderline prospect, one that will need some time in the minors after a somewhat disappointing college career.
