How do you improve upon a season in which you won a championship? LeBron James says the Heat can be even better. In last year's lockout-shortened season Miami went 46-20 -- a win percentage of 69.7 percent. In an 82-game season, that percentage works out to 57 wins. Can the Heat win 60 games or more? Do the additions of Ray Allen and Rashard Lewis and the return of Udonis Haslem make Miami a better team this season?
