Brian Wright and the Spurs' front office had themselves a busy offseason (that still may not be over) that included bringing several new players to San Antonio. While not every one of the team's acquisitions was necessarily a good move, overall, the Spurs had a successful offseason that will set the young core up for success.
With some of the team's centermost pieces of the past now off the team, next season may see frequent experimentation and lineup changes. Both the starting and bench units will look significantly different than they have in years past, and those differences may mean the team will get worse before getting better.
The front office did a much better job this offseason of constructing a roster that is more appropriate for playing modern, perimeter-focused basketball. That being said, the team's roster isn't endlessly versatile. The Spurs could run into a great deal of trouble during games if they were to have two or more incompatible players on the court together.
While the effectiveness of any given lineup will vary from game to game, the Spurs may find themselves in trouble more frequently than not by playing the following two pairs of players on the court with one another.
