David Stern has resided over four lockouts.
1995 lockout ended before the season started.
1997 lockout ended before the season started
1999 lockout resulted in 50 game season
2011 lockout resulted in 66 game season
By that measure Stern is already doing a better job than Bettman, nevermind that basketball players have much more leverage in negotiations than hockey players due to the popularity of the sport.
Either way though it's pretty much pick your poison. Stern and Bettman used to work at the same law firm, Proskauer Rose. That law firm represents management in labor negotiations for the NBA, NHL, NFL, and MLB, so get used to more lockouts. It's not a coincidence the NBA and NHL have been using similar strategies and tactics.
