There are only so many paths a team can go down to build a contender and none of them are fool-proof. Each one offers winding twists and turns that can lead to disaster before you even know it.
The Mavericks know this better than most, because they went so hard down one path they almost nuked their team into obscurity. When Dallas decided to try and bridge the gap from the Dirk Nowitzki era to the next one, they did so by trying to sign big name free agents to ride out the remainder of Dirk’s useful seasons and slowly transition the team over to whatever star they could grab with their gobs of cap space and supposed allure of organizational culture.
