The Oil Kings finished first in the Central Division and reached the WHL Finals against Western Conference champion Portland. Pollack did not skate in any playoff games.
2013-14: Pollock had a breakout season in his second year with the Memorial Cup champion Edmonton Oil Kings. Skating in 71 of 72 regular season games he scored 25 goals with 30 assists and was +18 with 36 penalty minutes. Edmonton tied Calgary atop the Central Division with 103 points, finishing second based on tiebreakers, then rolled through the WHL playoffs; defeating defending champion Portland in the finals. In 21 WHL playoff games Pollock scored 11 goals with 8 assists and was +11 with 10 penalty minutes. The Oil Kings lost two games during round robin play before defeating Val-d’Or in a semifinal game and then avenging a loss to Guelph in the championship to capture the Memorial Cup. Pollock had 2 assists and was an even plus/minus with 2 penalty minutes in five Memorial Cup games. He was ranked 34th amongst North American Skaters in the Central Scouting final rankings and was selected by Dallas in the second round (45th overall) in the 2014 NHL Draft.
Pollock can play center and wing, but the way he comes off the wall with his puck protection skills, he looks more like a winger. He can cut to the net hard and shield off would-be defenders despite not filling out his frame yet. He has a quick release and his snap shot is deceiving and accurate. Pollock uses his big reach and smooth hands to swashbuckle his way past defensemen. His skating is improved and it is now fitting his frame better. The strides are not long and exaggerated, but stubbier with more toe than heel. It is still a work in progress. He will need to improve his stamina, consistency and game-to-game craftsmanship as he continues to develop.
Pollock attended his first NHL training camp with the Stars before returning to the Oil Kings for the 2014-15 season. With several players moving on to pro hockey after last year's Memorial Cup championship, Pollock has moved into a leadership role on a team that is fighting to stay above the .500 mark. Scoring at a point-per-game pace in his third major junior season, he has been responsible on both ends of the ice. Long-term, Pollock's size and scoring skills suggest he can be an effective power forward at the next level.
