And Andrew, I do agree that some leads are, in fact, insurmountable in any practical sense. Suffice it to say, I haven't seen anyone go to the fouling tactic when they're on the losing end of a 25 point lead with 2 minutes left (at that point, getting the starters to rest, playing the young guys, avoiding injury all outweigh the potential benefit of winning one game).
To be honest, I don't really like dragging out games anymore than it has to. But knowing something incredible could happen at any moment--well, that's why we watch sports, isn't it?
Granted, it's not that common, though the Bucks/Nets game was kind of heading towards that territory. And you're right, the impossible is always incredible to watch, but it was pretty obvious it wasn't going to happen. The Bucks kept padding their stats and the lead stayed intact. When it got to 40 seconds and it was still going on, I thought it was a bit much.
This discussion goes, I think, to the essence of why we play the game. Do we play to win? Or, do we instead play for the ideal, artistic aspect of the game. And personally, my view is that the game of basketball, as James Naismith created, is a competitive sport in which the first and ultimate goal is to win. The artistic moments, the trancendent moments, arise precisely from that struggle when both sides gives (and takes) everything they can, as Kobe did when he took that three to tie, but when either side gives anything less, I feel like the resulting moment is tainted.
Certainly the object is to win. But when it comes to sports, there are also ideals and certain rules of competition that apply to all sports - the whole idea of "sportsmanship". You play to win but there's winning by any means necessary and then there's winning by absolutely any means necessary. Most people admire the athlete that possesses an incredible competitive drive but also respect for the game and its rules; the player or team that is very good at their sport and can win fairly simply because they are that good at what they do.
Conversely, we tend to scorn the player or team that frequently resorts to dirty tactics, no matter how talented they may be, because their victories come as a result of strategies that bend the rules of the sport and aren't sportsmanlike; players/teams who intentionally injure their opponents or employ other cheap/dishonest methods that they can creatively get away with.
I know the Nets weren't trying to do that, but the point I'm trying to make is that while competition is an important part of sports, so is the concept of goodwill and sportsmanship. The Bucks/Nets game may not have been an example of horrible sportsmanship because they were admittedly employing a strategy that can be considered respectable gamesmanship, but I feel in that particular instance the use of that technique quickly become a tactic that tight-roped the line of sportsmanship because the Nets weren't really making a concerted effort to win aside from fouling. Really, all they were doing was making the Bucks' win a chore. Fouling was doing them no favours, yet they kept doing it.
