Haula is an incredible college hockey player. In my opinion he has been far and away the best player on a STACKED Gopher team this year that includes guys like Nick Bjugstad, Kyle Rau, Zach Budish, Nate Condon etc.
His two perceived "weaknesses" early in his Gopher career were a lack of consistent scoring and an unwillingness to shoot the puck, but he has since turned those into strengths. He's been the most consistent player on the team, scoring in all but 5 of the 33 games he has played in. He also shoots the puck more than anyone on the team. He has 127 shots which is second to Nick Bjugstad's 132, but Haula missed 3 games with hand injury. After his freshman year, the Gopher coaches made it clear that he needed to start shooting the puck more and since then he's been a different player. He's great on the power play and the penalty kill and there's very little he can't do at the college level.
The question is how will it translate to the pros? He's a little undersized and he doesn't really have any elite skills other than maybe his hockey sense. He's a very good passer and he really sees the ice well. He's not incredibly fast but he has a very accurate shot and he knows when to use it. He's a guy that does everything well and I wouldn't be surprised if he found success at the NHL level.
