ben wallace in a kings uniform is a much greater pipe dream than kevin garnett, imo. at least in minnesota it is clear that they aren't going anywhere. that is, of course, no fault of garnett's, but that franchise is probably looking for a change, despite all of the boldfaced statements from management that garnett isn't going anywhere. and if they don't trade garnett in the offseason, and if the team is still a loser come next february, then look for garnett to demand a trade.
as for ben wallace, he's on a championship contender. and its not just any championship contender, its the best team in the league. and it really isn't just any "best team in the league." the lakers were the best team in the league during their most recent "dynasty," but they didn't have the chemistry that this pistons team has. the pistons of the last few years are an incredible example of the proper way to construct a basketball team. it helps that they all enjoy playing the same hard-nosed style, and ben wallace is, quite possibly, the biggest factor in keeping that team aggressive. he ain't going anywhere. free agency? meh...consider him locked up regardless.
though it is fun to dream. ron artest and ben wallace on the same team? wooooo...that would be exciting, and quite a strange situation of intrateam competition for defensive player of the year, dontchya think?
