2011-12: Mistele skated in 12 of 13 playoff games for Plymouth after seeing limited ice time with the Whalers during much of his first OHL season. In 28 regular season games he scored 3 goals with 2 assists and was +2 with 33 penalty minutes. The Whalers finished first in the West Division and reached the second round in the playoffs. Mistele scored 2 goals with 3 assists and was +1 with 11 penalty minutes in the playoffs.
2012-13: Mistele led the Whalers with 34 goals and was one of three players to skate in all 68 regular season games in his second season with Plymouth. He finished +32 and had 26 assists and 69 penalty minutes as Plymouth again finished first in the West Division. The Whalers reached the Western Conference finals against OHL champion London. Mistele appeared in 9 of 15 playoff games — receiving a six-game suspension for a hit to the head in the first round against Sarnia. He scored 3 goals with 2 assists and was an even plus/minus with 8 penalty minutes in the playoffs.
2013-14: Mistele returned to Plymouth for his third season with the Whalers. The team’s fifth-leading scorer despite missing time early in the season due to a suspension, he scored 18 goals with 19 assists in 56 games and was -4 with 59 penalty minutes. Plymouth finished fourth in the West Division and lost to eventual OHL champion Guelph in a first round series. Mistele had 2 assists and was -3 with 2 penalty minutes in five playoff games. He was selected to play for Team Cherry in the 2014 CHL/NHL Top Prospects Game. Mistele was ranked 88th amongst North American skaters in the Central Scouting final rankings and was selected by Los Angeles in the sixth round (180th overall) in the 2014 NHL Draft.
2014-15: Mistele returned to Plymouth for his fourth season Whalers before being acquired by eventual Memorial Cup champion Oshawa at the OHL trade deadline. In 60 regular season games between the two teams he scored 37 goals with 27 assists and was +8 with 34 penalty minutes. The Generals finished first in the East Division, winning 51 of 68 games, and rolled through the OHL playoffs; defeating Erie in the finals. Mistele scored 13 goals with 3 assists and was +5 with 18 penalty minutes in 21 playoff games. In four games at the Memorial Cup he was +4 with 1 assist and 4 penalty minutes. Oshawa defeated WHL champion Kelowna 2-1 in overtime in the championship game.
2015-16: Mistele attended his second training camp with the Kings before returning to Oshawa for an overage season. Struggling to start the year with many of the players from the Memorial Cup championship team moving on to pro hockey, the Generals traded Mistele to Sarnia in December for three future draft picks. Mistele scored 8 goals with 8 assists and was -10 with 16 penalty minutes in 19 games for Oshawa. He scored 25 goals with 17 assists and was +4 with 29 penalty minutes in 42 regular season games for Sarnia. The Sting finished first in the West Division before being upset by Sault Ste. Marie in seven games in the first round. Mistele scored four of his 6 goals on the power play with 4 assists and was +1 with 10 penalty minutes in the playoffs.
Mistele has the prototypical size and attitude of a power forward and is an opportunistic goal scorer. His game fits in well with the hard edge, combative style that the Kings play as he is willing to go into the smaller areas and along the walls to retrieve the puck. His mobility and agility are areas that need to continue to improve for him to compete successfully at the NHL level. Mistele can be undisciplined in his exuberance at times.
Mistele ended the 2015-16 season with the Sarnia Sting after being acquired from Oshawa in a December 2015 trade. Not signed to an entry-level contract with the Kings, Mistele is an unrestricted free agent. A proven goal scorer in the OHL, he must continue to refine the supplementary areas of his game to be a solid second or third line winger at the NHL level.
