Tuesday is Gary Bettman's 20th anniversary as NHL commi sioner. (Getty Images) Tuesday is a big day for Gary Bettman as he celebrates his 20th anniversary as NHL commi sioner.It was Dec. 11, 1992, when the NHL board of governors , and what a ride it's been ever since.No matter what happens for the rest of his time as the NHL's top man, he will forever be remembered for the Dermontti Dawson Jersey three lockouts that have taken place during his watch, whether they're all his doing or not Pittsburgh Steelers Jersey -- and the NHL's owners, and yes, even players, certainly have to share quite a bit of blame. That includes the current one, which has cost the league 526 regular season games during what should have been the 2012-13 season.Add that total to the previous two lockouts, including the 2004-05 work stoppage that eliminated the entire season, and the NHL has mi sed 2,224 regular season games over 511 (and counting) days during Bettman's watch. No other sports league has mi sed more than 938 regular season games over that same time period. Impre sive track record. Bettman has Roosevelt Nix Jersey never been popular among hockey fans, and to prove that, here is video of them relentle sly booing him over the years.The NHL has changed quite a bit over the years under Bettman's watch. We no longer have tie games or the two-line pa s. We do have shootouts, the trapezoid, the loser point in the standings, and the Winter Cla sic (well, not this year).The league went from 24 teams in 1992 to Joe Haden Jersey 30 in 2012. NHL hockey is now played in every corner of North America, including cities like Denver, Columbus, and Phoenix, but is no longer played in Hartford or Quebec. Winnipeg lost a team and gained another; ditto Minnesota. Atlanta gained a team and lost it.Regarding all of the expansion, that's one area Bettman gets a bit too much criticism for (the expansion into the southern and western markets) as that was starting to take place well before he was named commi sioner. The league was already expanding into those areas and it Rod Woodson Jersey was going to continue taking place whether Bettman was commi sioner or not.Teams like Tampa Bay and San Jose were already in existence, the Minnesota North Stars already had one foot out the door, and the Florida Panthers and Anaheim Mighty Ducks were on the verge of becoming a reality.
