2003-04: Lashoff began his junior career with Kitchener of the OHL. He scored 5 goals with 19 assists and was +2 with 97 PIM in 62 games. He had one assist and was -5 in five playoff games for the Rangers. Lashoff was named to the OHL Second All-Rookie Team.
2004-05: Lashoff missed much of the season due to a case of mononucleosis but he put up decent numbers on a strong Kitchener Rangers team. In 44 games, he scored 4 goals with 18 assists and was +16 with 44 PIM. He was a regular in their top four and played in a lot of situations. Three of Lashoff’s four goals were scored with the man-advantage. Lashoff had 3 assists and was +4 with 18 PIM in 13 playoff games for Kitchener. He played in the 2005 CHL Top Prospects game. Lashoff was selected by the Boston Bruins in the first round (22nd overall) of the 2005 NHL draft.
2005-06: Lashoff returned to Kitchener and was a team-leader for the second-place Rangers. While he once again missed time due to injury, Lashoff scored 7 goals with 40 assists and was +8 with 146 PIM in 56 games. He was especially productive on the power play where he scored 2 goals and had 28 assists. In five playoff games for Kitchener he scored 1 goal with 1 assist and was +1 with 12 PIM. He signed a three-year, entry-level deal with the Bruins following the OHL season and joined their AHL affiliate in Providence. In seven games with the P-Bruins, he had 1 goal with 1 assist and was -2 with 6 PIM. In six AHL playoff games, he was scoreless and -5 with 6 PIM.
2006-07: Lashoff had an impressive first full season in pro hockey. After opening the season with the Bruins, he spent the majority of the season in Providence where he was named to the AHL All-Rookie team and was Providence’s lone representative in the AHL All-Star game. At the NHL, Lashoff saw regular time in the Bruins’ first five games of the season but then saw limited ice-time before being returned to Providence. He had a second five-game call-up in January. In 12 games with Boston he had 2 assists and was -6 with 12 PIM. In the AHL, he led all Providence defensemen in scoring with 11 goals (nine on the power play) and 25 assists and was -6 with 12 PIM in 64 games.
2007-08: Lashoff saw time with the Bruins in four separate call-ups and continued to play a major role on Providence’s blueline at the AHL level. He scored his first NHL goal, on the power play, on December 31st versus the Atlanta Thrashers and finished with 1 goal with 4 assists and was -2 in 18 games with Boston. With Providence, he was named to the PlanetUSA AHL All-Star team for the second consecutive season and scored 9 goals with 27 assists and was +11 with 79 PIM in 60 games. In the playoffs, he had 4 assists and was +2 with 6 PIM in nine games for the P-Bruins.
2008-09: Lashoff began the season in Providence before being called up by the Bruins in December. He was returned to Providence in January then traded to the Tampa Bay Lightning in March along with Martins Karsums for Mark Recchi and a 2010 second round pick. In 16 games with the Bruins, he had 1 assist and was +1 with 10 PIM. With the Lightning, Lashoff saw full-time ice for the first time in what amounted to a 12-game tryout – including back-to-back games in April in which he played over 27 minutes. In those games he had 7 assists and was -7 with 10 PIM. In 35 AHL games, all but two with Providence, he scored 5 goals with 16 assists and was -3 with 38 PIM.
2009-10: With 2009 first-round pick Victor Hedman grabbing a spot with the Lightning in camp, Lashoff found himself back in the AHL in his first full season in the Tampa Bay system playing all but five games with Norfolk. After being re-called on March 31 by the Lightning, he saw limited ice time in all but one of the five games he played in – and finished -2 with 21 PIM – the bulk of which came in his first game with the Lightning when he received a game misconduct for boarding just 2:22 into the game. In 68 games with the Admirals, he scored 8 goals with 16 assists and was -18 with 105 PIM.
Lashoff has the blend of skating, size and technical skill to be an outstanding two-way, puck-moving defenseman. He has been a power play threat at the lower levels of hockey and is a confident and smooth skating playmaker. He’s at his best when he has the puck, sees the ice well and is solid on both the power play and penalty kill. Lashoff plays an aggresive style that sometimes crosses the line into undisciplined. His decision-making and awareness without the puck are sometimes suspect, particularly in the defensive game. He has the skill level and desire to be a top four NHL defender that contributes to the offensive attack but has not yet put it all together.
Lashoff enters his second Lightning training camp in a group of defensemen looking to seize a job under new coach Guy Boucher. Lashoff brings an offensive game that would fit well with some of the gifted forwards in Tampa Bay but has yet to prove that he can be competent enough in his own end. Though he is entering his fourth season of pro hockey, he is still only 23-years-old so there is still potential for improvement. Though he may never reach the top pairing potential that made him a first-round pick in 2005, Lashoff has the skill to be a full-time defenseman at the NHL level.
