Alexander Frolov was drafted in the first round (20th overall) of the 2000 NHL Entry Draft draft by the Los Angeles Kings. He made his NHL debut in 2002 for the Kings, scoring his first NHL goal in his seventh game on 25 October 2002. Frolov became a restricted free agent before the 2005-06 NHL season and he and the Kings had initial difficulties in agreeing on a new contract. He then signed a one-year contract with a Russian league team, saying that he would most likely go on to spend the 2005-06 season playing in Russia. However, a month later he signed a 5-year $14.5 million contract with the Kings.
Frolov was named to Russia's 2006 Men's Ice Hockey team for the 2006 Winter Olympics. During a round-robin game versus Kazakhstan, he suffered a partially separated shoulder and missed the rest of Russia's games during the Olympics. He also missed 10 of the Kings' games once the NHL season resumed.
The 2006-2007 season was certainly the best for Frolov, as he scored 71 points in 82 games (35 goals and 36 assists). Frolov is a skilled player that continues to produce on a promising team in the Los Angeles Kings. Along with Anze Kopitar, Frolov could emerge as one of the league's top offensive talents. He has loads of high end skill and is very fast. Frolov could use a little bit more in the physical department, as it seems he can't handle rough play very well. Still, he's still a young player and that will come with experience and time.
