2008-09: David Broll played 73 games with the Toronto Young Nationals (Midget AAA) and scored 31 goals with 26 assists. Broll was selected by the Erie Otters in the first round (10th overall) of the OHL Priority Draft.
2009-10: Broll scored 9 goals with 9 assists as a rookie with the Erie Otters. Four of his 9 goals came on the power play and he finished -10 with 42 PMs. Erie, after finishing fourth in the Midwest division in the regular season, was swept by eventual OHL champ Windsor in the first round of the playoffs. In four playoff games, Boll was scoreless and -2 with 2 PMs. Broll played for silver medal-winning Team Ontario in the World Under-17 Hockey Challenge and had 2 assists with 14 PMs in six games. Broll was invited to Team Canada’s U-20 tryout camp.
2010-11: Broll scored 8 goals with 14 assists in 41 games before a mid-season trade to Sault Ste. Marie. While the Greyhounds failed to make the playoffs, the move seemed to have a positive effect on Broll, who was +1 in 24 games after being -11 with the Otters prior to the trade. Broll scored 5 goals with 7 assists and 34 PMs with the Greyhounds. Broll slipped from 78th in the midterm rankings to 139th in Central Scouting’s final rankings of North American skaters and was selected by the Maple Leafs in the 6th round (152nd overall) of the 2011 NHL Draft. Broll signed a three-year, entry-level contract with Toronto in July 2011.
2011-12: Broll made his pro hockey debut, appearing in three late season games and two playoff contests for the AHL's Toronto Marlies following his third junior season in the OHL. He had one major penalty with no points in limited ice time with the Marlies and was minus-one in two playoff games. Broll scored 8 goals with a career-high 25 assists in 59 game in his first full season with the Sault Ste. Marie Greyhounds and was plus-six with 18 penalty minutes. The Greyhounds finished fifth in the West Division – one point behind Windsor for the final playoff spot.
Broll was highly regarded coming out of midget hockey and it was anticipated that with his size and good hands he could be a big-time scoring power forward. A hard-working, two-way player, he has been a physical presence in his two years in the OHL but has not yet put up big scoring numbers and is a bit lacking mobility-wise. He uses his size to advantage and can handle the puck in small spaces but his limited skating ability and lack of consistency have limited his production to this point.
Broll will return to the Soo Greyhounds in 2012-13 for his fourth season in the OHL. Broll is a leadership-type player and seemed to benefit from an increased role with the Greyhounds. He has slipped some in the eyes of scouts since his midget days but the Leafs are hoping that he will become the prototypical power forward his skills and size suggest he can be. At this point it looks like his pro role, at least initially, will be that of an energy line, forechecking forward and potential enforcer.
