Ain't like any of those guys ever won a title or made an All-NBA team. And they all had careers of similar length. So you're basically looking at: how much playoff success did they have and how much did they matter to good teams?
Al Harrington started 7 playoff games in his entire career. He wasn't a guy that mattered at any point.
Jamison only saw the second round twice, and one of those times was when he was with the Cavs and absolutely sucked.
Rashard actually mattered as a scoring stretch four for a little bit, especially when he went to Orlando. But he was a tool that was used well a couple years, it wasn't like he was leading that team.
Cuttino? Ricky Davis? You serious?
You pretty much just listed some guys who racked up mediocre scoring totals for shyt teams and called that a career. Harrington and Mobley NEVER mattered in the NBA like that. Jamison and Rashard were, at best, sidekicks on suspect rosters.
In 2002 Bibby was a clear top-two player for a team that was up 3-2 in the WCF and was one fixed quarter away from an NBA title. The next year he took the 2003 Mavs to 7 games even after Webber got knocked out for the season in game 2. Then they were one Peja three....TWICE... from beating the 2004 Timberwolves. When he went to the Hawks he immediately pulled them into the playoffs and took the 66-win Celtics to 7, then beat Wade the next year. He was the starting point guard for ten playoff teams and won nine playoff series.
Again, none of these guys were ever All-NBA level or won a title. But Bibby actually led good teams, was a player that mattered from the beginning of his career to the end. If you measure a career by how much winning you do and how much you personally contribute to that winning, Bibby easily had the beast career of them.
