It's amazing to think back to the 2006-2007 team; I figured at the time that there was a lot of talent there that just needed some time to develop, but if you put that team back together on the court in 2013 you'd be lucky to win 25 games.
Rondo, Allen, Pierce, Jefferson, Perkins started on playoff teams and Baby was a very productive starter as well. That's a lot of talent with no lottery picks outside of Pierce.
considering Perk and Powe weren't injured at that time so taking that into consideration for evaluating that core of talent developing:
Rondo, Allen, Pierce, Jefferson, (healthy) Perkins
Bench: Delonte, Telfair, Gerald Green, (healthy) Powe, BBD (assuming that with only 1 second rounder Danny takes BBD over Pruitt)
That's a playoff team in the East. Not a contender but a playoff team.
Add Jeff Green with the 5 pick the next year and it's a very good playoff team. still not a contender but there was reason to believe the team had talent
