The failure would be keeping a player just to save face. A lot of franchises do that and it puts them back years because they just don't want to admit a mistake.
Even the Spurs have made this mistake. Think back to the training camp in 2000. The final spot on the roster came down to Chris Carrawell, Derrick Dial or Raja Bell. Carrawell and Dial were both second round draft picks. Carrawell was a player who was expected to be picked in the middle of the first round. The only reason he slipped was because he didn't work out for teams who drafted after 19. The Spurs picked him in the second round and were very happy ... even though they never worked him out. Derrick Dial was a second round pick that played in Italy the year before and put up very good numbers overseas. Raja Bell was just some guy that Pop liked who had no ties to the Spurs and his resume was unimpressive.
Back then, the
Brunos of the forum were all

ing when reports came out that Carrawell was struggling and the Spurs were thinking of cutting him. Carrawell even had guaranteed money in his first and second year of his contract. Luckily, the Spurs swallowed their pride and made the right decision in cutting him. Then it came down to Dial or Bell. RC Buford had scouted Dial in Europe and loved what he had seen. Pop went on record as saying Bell was the most impressive two-guard in camp. Buford overruled Pop and decided to keep Dial instead of Bell because Dial had went to Europe when the Spurs asked him to and because the Spurs had "too much invested" in Dial.
