Danny is crazy if he thinks that Person + Williams + Stipanovich for Larry Bird was a fair trade.
We're talking about either the '87 or '88 season. In '87, the Celts made the Finals, and Larry averaged 28p / 9r / 8a / 2s / 1b, on 53% / 40% / 90% shooting. In '88, he basically averaged the same.
It's the equivalent of trading Lebron James for Jeff Green, Avery Bradley and Jared Sullinger.
